527,075. Reaction products of rubbers. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). Dec. 19, 1938, Nos. 36928/38, 15971/39 and 32189/39. [Class 70] [Also in Group IV] Multi-unsaturated organic compounds of high molecular weight (at least about 5000) are reacted with inorganic acids or anhydrides {except those of highest state of valency where the acid-forming element has more than one valency) in the presence of liquid organic compounds containing " ether like " oxygen atoms {i.e. oxygen atoms linked by single bonds to each of two carbon atoms). Suitable initial bodies are polymers of butadiene, acetylene and their substitution products and homologues and co-polymers of these substances with other unsaturated bodies such as olefines, styrene, vinyl esters, acrylic and methacrylic acids and unsaturated aldehydes, ketones and ethers, and also natural rubber. Suitable inorganic acids and anhydrides are phosphorous, sulphurous, and nitrous anhydrides and acids ; hydrogen sulphide and halogen hydrides, but mixtures which produce free sulphur (such as SO 2 +H 2 S) are excluded. Activating agents such as metal salts which form addition compounds with ether-like compounds may also be present. The reaction may be effected in the presence of a solvent or solvent mixture which may itself contain an ether-like compound. In examples (1) SO 2 is passed into butadiene polymer in benzene and dioxane is added (3) rubber in benzene is treated with SO 2 and dioxane ; (4) a divinyl acetylene polymer is treated similarly ; (5) hydrogen sulphide is passed into butadiene polymer in dioxane ; (6) butadiene polymer in dioxane is coagulated in a bath containing acetic acid, water, and sulphur dioxide ; (7) a bath containing methanol, water, and sulphur dioxide is used for coagulating butadiene polymer solutions in a dioxane alone and together with di-isopropyl ether, diethyl acetal, paraldehyde, diethyl ether, pentane, carbon disulphide and benzene respectively ; (8) NO+NO 2 is passed into butadiene polymer in dioxane, isopropyl ether and benzene, methyl propene methylene dioxide, ethene methylene dioxide, and dioxane and isopropyl ether respectively, butadiene polymer in dioxane is coagulated in (9) aqueous sodium nitrate and hydrochloric acid, (10) aqueous phosphorous acid (11) nitrous acid saturated with SO 2 (12) mixtures of menthanol, water and SO 2 containing FeSO 4 FeCl 3 and MnSO 4 respectively, but CuSO 4 and ZnCl 2 may also be used ; (13) a solution of butadiene polymer in dioxane is spun upwardly into a vertical tube filled with a coagulation liquid consisting of ethyl and benzyl alcohols and water saturated with SO 2 (14) the same dutadiene polymer solution into ethyl alcohol saturated with SO 2 ; (15) butadiene polymer in dioxane is injected into a coagulation bath containing boron fluoride, acetic acid and SO 2 ; (16) butadiene polymer in dioxane and paraldehyde is injected into liquid SO 2 at -15‹C. ; (17) butadiene polymer in dioxane is spun into a vertical tube filled with SO 2 at 60‹C.; (18) neoprene and butadiene polymer in dioxane is coagulated in a bath containing methanol, water and SO 2 to produce films ; (19) butadiene polymer and ethyl cellulose or cellulose acetate in dioxane is coagulated in the same mixture ; (20) butadiene polymer in dioxane is poured into a silk gauze and SO 2 + CO 2 is passed over the film, leaving a gastight layer ; (21) linen is boiled in dioxane and then immersed in butadiene polymer in dioxane containing Igepon T,"Igepon" being a Registered Trade Mark, the material being then pressed and passed into a bath containing methanol, water and SO 2 washed and dried, this treatment increases the crease stability.

145 Improvements in shaped bodies, such as thin sheets, threads or the like, composed essentially of rubber hydrochloride and methods of producing such bodies GB1192237 1937-04-26 GB497788A 1938-12-28
497,788. Halogenated rubber ; compound sheet materials ; yarns etc.; catgut substitutes. MINICH, H. D. April 26, 1937, No. 11922. Convention date, April 30, 1936. [Class 70] [Also in Groups VIII, IX, and XXV] Rubber hydrochloride bodies, particularly in the form of thin sheets or threads, are heated to a temperature at which they are plastic (150-230‹ F.), stretched in one or more directions, and cooled while stretched to solidification temperature ; this makes them stronger, more resilient, more tear-resistant, lustrous and crackly. A film may be stretched to 2-6 times its original length. The process may be repeatedly applied to a sheet or to a plurality of sheets. Transparent strips 21 and narrow red strips 22 are assembled in a funnel 30, passed over a heating cylinder 32, under an auxiliary heater 41, and through a cooler 34, and stretched by rollers 35 which rotate faster than rollers 31. The strips fuse into a homogeneous strip. The slots 28 in the assembly plate 27 and the exit end of the funnel 30 may be narrower than the widest sheet fed therethrough, so that the edges of the said sheet are rolled over and beads are formed on the finished article. The surface of the cylinder 32 may be grained or ribbed, and the surface of one or both of the idler rollers 42, 43 may be provided with ornamental or other designs. One or more of the intermediate layers may be imprinted or perforated. The relative speeds of the sheets may be varied, e.g. by rotating the upper of the rollers 35 or 31 at a higher or lower speed than the lower. The drive of the heating cylinder 32 may be correlated with the drive of the rollers 31 or 35 or both. In making laminated coalesced films coloured films may be placed above, below or between other films, e.g. between transparent films ; opaque films may be placed under or between one or more coloured or transparent layers. Several films which have been stretched laterally and longitudinally are superposed in crosswise grain directions and again stretched and fused together under pressure ; longitudinal ribs may be produced in such laminations by inserting between the films, before stretching, narrow unstretched strips. A sheet is obtained by coalescing superposed layers of stretched and unstretched material while they are being stretched and heated to a plastic state and releasing them while they are plastic ; a strip having a crinkled central surface and ruffled edges may be obtained by thus treating two narrow pre-stretched strips enclosed between two wider unstretched strips. Compound sheet or strip material may be used in making shower curtains, raincoats, table covers, umbrella coverings, wall covering, packing material and dress goods. Narrow untreated strips may be rolled back and forth as they are moved over a heated surface and stretched as they are drawn away from it ; the thread so produced may be used as a substitute for gut for surgical sutures, musical strings, stringing racquets, leaders in angling and fishing lines and nets. Several ribbons of the rolled stretched material may be twisted together while being heated and stretched. A strip of untreated material may be twisted with a strip of pre-stretched material while the two are heated and stretched. The rubber hydrochloride may be made by dissolving 5 to 7 parts of rubber in 100 parts (by weight) of a solvent, e.g. benzene, and maintaining the solution at 50‹ F. for 6 hours while dry HC1 gas is passed through it. The treated solution is left for 24 hours at room temperature and the solvent and excess HC1 are then driven off by steam distillation or by passing nitrogen or air through the solution. The mass is washed with ammonia solution and water and the residual mass of rubber hydrochloride and ammonium hydrochloride is dried under vacuum. A film is obtained by making a 5 per cent by weight solution in, e.g. chloroform, which may contain a dye (or opaque, insoluble colouring matter) and an age-resister, e.g. cyclohexylamine formaldehyde, running the solution on to a moving belt surfaced with cellulose acetate or celluloid, removing the solvent by passing a stream of air over the surface and continuously stripping the film from the belt. Alternatively the rubber hydrochloride may be made by subjecting thin sheets of washed, milled, pale crepe rubber to the action of dry HCl gas at pressures up to 8 atmospheres at 180‹ F. for 12 to 48 hours, releasing the residual free HC1 and removing all traces of HC1 by heating under vacuum. In a third method, washed, milled, crepe rubber is treated with dry, liquid HC1 at low temperature, the required high pressure effecting hydrochlorination almost instantaneously. The Specification as open to inspection under Sect. 91 comprises also the application of the invention to bodies made of halogenated and hydrohalogenated butadiene bodies in general, e.g. the products of the reaction of HBr, HI, chlorine, bromine and iodine with rubber, guttapercha, balata, isoprene, erythiene, " chloroprene '' and the substance known under the Registered Trade Mark " Duprene." This subject-matter does not appear in the Specification as accepted.

149 DIRECT METHOD FOR PREPARING SYNDIOTACTIC 1,2-POLYBUTADINE ZA87158 1987-01-09 ZA87158B 1987-08-26 BELL ANTHONY JOSEPH
Short fibers of syndiotactic 1,2-polybutadiene are utilized in making tires that have improved resistance against heat build-up and improved wear characteristics. The preparation of syndiotactic 1,2-polybutadiene in fibrous form has traditionally involved an extrusion and stretching step. However, the technique of the present invention circumvents the necessity of hot mill flexing and/or extrusion in making fibrous syndiotactic 1,2-polybutadiene. The present invention more specifically involves a process for preparing syndiotactic 1,2-polybutadiene fibers directly comprising polymerizing 1,3-butadiene monomer in the presence of (1) a catalyst composition which is comprised of (a) a cobalt compound and (b) an organoaluminum compound; (2) carbon disulfide; and (3) at least one member selected from the group consisting of liquid polymers and naphthenic oils.

A solution of a sulphochlorinated polyolefine is spun into a primary or secondary diamine or into a solution of a primary or a secondary diamine in a solvent which is miscible with the solvent of the spinning solution. The polyolefine may be polyethylene, polypropylene, or an ethylene/propylene copolymer. The polymer solvent may be an aromatic hydrocarbon, a light petroleum spirit, or a halogenated hydrocarbon such as chlorobenzene chloroform or carbon tetrachloride. The last-named solvent is especially advantageous since the polyolefine is dissolved therein for sulphochlorination. The diamines (which cross-link the sulphochlorinated polyolefines) may be primary or secondary aliphatic, aromatic or araliphatic diamines, aliphatic diamines being used with special advantage. The carbon chain of the diamines may also be interrupted by bridging elements or groups such as oxygen or the carbonyl group. The amines which may be used include phenylenediamines, 4,41-diaminobenzophenone, xylylene diamine, the diaminodecanes, 2,21-diamino-diethyl ether, and N,N1-dimethyl-ethylene-diamine. Diamines having a chain of 2 to 6 carbon atoms are used with special advantage. In the preferred wet spinning process, the diamine solvent used for the coagulating bath may be a monohydric short-chain alcohol and/or a low molecular weight ketone. The coagulating bath may contain a compound such as a tertiary amine or sodium bicarbonate to neutralize the hydrochloric acid formed by the reaction between the sulphochlorinated polyolefine and the diamine which takes place in the bath. The filaments formed in the bath may be washed by passing them through a bath of hot water and stretched.
