101 Process for Production of Modified Poly-(Methylene Sulphide) GB3038669 1966-11-07 GB1171453A 1969-11-19
1,171,453. After-treatment of polythiomethylenes. STAUFFER CHEMICAL CO. 7 Nov., 1966 [15 Nov., 1965], No. 30386/69. Divided out of 1,171,452. Heading C3P. Mercapto-terminated polythiomethylene is reacted with an acyl halide, anhydride or a hydrocarbyl halide with elimination of hydrogen halide or organic acid. Termination results from reaction with monofunctional reagents, while coupling to increase molecular weight occurs with difunctional reagents, the use of phthalyl chloride being mentioned. In the examples polythiomethylenes are stabilized by reaction with acetic anhydride in the presence of sodium acetate or benzoyl chloride, chlorobenzene, or p-dibromobenzene in dimethylacetamide and in the presence of pyridine or potassium hydroxide (presumably as hydrogen halide absorbers).
102 Polymers containing gem dithioether and gem diether and/or ether groups and process for the preparation thereof GB3825466 1966-08-25 GB1086977A 1967-10-11
Polymers having in their backbone consecutively alternate gem dithioether, gem diether and/or ether groups each separated one from another by divalent organic groups are prepared by reacting a mercaptoalcohol and a carbonyl compound in the ratio of mercaptan to carbonyl groups of 2:1 to 1:1 in the presence of a strong non-oxidizing acid having a pka of 2.5 or less and in the substantial absence of added water and separating out the polymeric reaction product formed thereby by removal of the water by-product. The reaction proceeds by first forming a dihydroxy gem dithioether which then reacts with excess carbonyl compound to form a polymer containing alternate gem dithioether/gem diether groups which is then isolated by cautious removal of water and any solvent present or alternatively molecules of dihydroxy gem dithioether compound and/or the hydroxyl containing alternating gem dithioether-gem diether linked polymer may be joined together by forcible removal both of the water of reaction formed in the first step and the water formed by etherification of hydroxyl groups, at elevated temperature and in the presence of a strong non-oxidizing acid. Suitable carbonyl compounds have the formula wherein R and R1 may be hydrogen or hydrocarbon groups containing 1 to 25 carbon atoms and are preferably formaldehyde, acetaldehyde, benzaldehyde, acetone or methyl ethyl ketone. Preferred mercaptoalcohols are mercaptocyclobutanol, 3,6-dimercaptopentamethylene glycol mercaptopropanol, 1,2-dihydroxy 3-mercaptopropane and especially 2-mercaptoethanol. Useful strong acids are sulphuric, hydrochloric, p-toluene chlorosulphonic and trichloroacetic acids. Solvents which may be used are nonane, decane, benzene and toluene. The hydroxyl group containing polymers obtained above may be reacted with polyisocyanates in an NCO/H ratio of 0.75:1 to 3.1 in order to produce polyurethane prepolymers or rubbers. Conventional polyisocyanates may be used.

Poly (methylene sulphide) having repeating CH2S units is prepared by reacting hydrogen sulphide and formaldehyde in the presence of a catalytic amount of a water soluble metal salt of trithiocarbonic acid. Poly (methylene sulphide) containing repeating CH2S units, in the form of a free flowing white powder with a m.p. generally above 220 deg.C. The thermal stability may be improved by reacting with agents which either give terminal ethylsulphonyl, acyl, or hydrocarbyl groups, or give polymers in which the CH2S units are interrupted by these groups. The modified polymers are suitable for the prodn. of fibres, extrudates, and mouldings.
104 Thermoset resins and intermediates therefor GB667364 1964-02-18 GB1027056A 1966-04-20
Glycol formthionals where X is O or S, n is an integer and the unit has an average molecular weight of 77-107 and a sulphur content of 43-65%, are prepared by saturating formalin with H2S at pH 3-9 below 15 DEG C. A preferred mixture contains largely HOCH2SCH2OCH2OH and HOCH2SCH2SCH2OH in approximately 3 : 1 mole ratio. Water-soluble resins may be obtained by heating together substantially equimolar amounts of urea and glycol-formthional at pH 4-6 below 60 DEG C. until traces of solid appear. These polymers contain units apparently fewer than 100, probably fewer than 10 per molecule, on average.ALSO:A thermosetting resin comprises 40-100 weight per cent of a glycol-formthional/urea resin having repeating units where X = O or S, n is an integer, and the unit has an average molecular weight of 77-107 and a sulphur content of 43-65%, and 0-60% complementally of a natural polyacetal of recurring unit and/or an aminoplast resin as filler, and/or an epoxy compound or epoxy resin as stabilizer and/or a polybasic acid anhydride as hardener. The glycol-formthionals are prepared by saturating formalin with H2S at pH 3-9, below 15 DEG C. Water-soluble, A-stage, glycol-formthional/urea resins are obtained by heating substantially equimolar amounts of urea and glycol-formthional at pH 4-6, below 60 DEG C., until traces of solids appear. The pH of the solution may be stabilized by addition of phenolic antioxidants, e.g. 2,6-di-t-butyl-4-methyl-(or -methoxy-) phenol. These polymers apparently contain less than 100, probably less than 10, units as above. Solutions of these resins may be used with or without modifiers to laminate coat or impregnate substrates, and may be thinned with organic solvents, e.g. alcohols, ketones, ethers. They may be mixed with reactive fillers, e.g. starch, cellulose, melamine/formaldehyde, guanidine/formaldehyde, benzoguanidine/formaldehyde, biguanide/formaldehyde, guanylurea/formaldehyde, biuret/formaldehyde or urea/formaldehyde. a -Cellulose is preferred, amounting to up to 55% by weight of the resin/filler mixture, and may be precoated with a melamine/formaldehyde or benzoguanidine/formaldehyde which is cured before the filler and the resin are mixed. Non-reacting fillers also may be added, e.g. carbon black, glass, asbestos, silica, cadmium red, cadmium yellow, TiO2, or phthalocyanine green, and lubricants, e.g. MoS2, polytetrafluorethylene or glycerol monostearate. A water-insoluble B-stage resin still capable of being shaped may be obtained by heating the A-stage resin mixture at pH 3-6, below 60 DEG C., losing volatiles until less than 3 weight per cent of water remains. This resin may then be milled and stabilized by treatment with epoxy compounds or resins, e.g. glycidyl ethers, or low molecular weight condensates thereof with phenols or polyols, which may be applied by spraying, followed by an acetone solution of a volatile organic acid. Hardeners, e.g. maleic, pyromellitic or phthalic anhydride, may similarly be added at this stage. Solid C-stage resins are obtained by heating the B-stage resins at 60-180 DEG C. under pressures up to 15,000 p.s.i. In examples A-stage resins are used to laminate paper and birch veneers. B-stage mixtures are made, using as filler a -cellulose impregnated with a melamine/formaldehyde precondensate, and incorporating minor amounts of glyceryl monostearate and TiO2; these are dried and ground and sprayed with nonylphenol glycidyl ether in hexane, formic acid in acetone, and phthalic anhydride is finally added. Cure is at 140 DEG C. and 3000 p.s.i. A cup and saucer are made from this powder.

108 Improvements in or relating to the manufacture of artificial resins GB2678035 1935-09-27 GB463433A 1937-03-30
A synthetic resin is prepared by condensing urea with formaldehyde in the presence of sulphur, preferably in alkaline solution. Moulding powders may be formed from the resin together with acid accelerators, pigments, plasticizers, and fillers such as wood flour, cellulose or ground wood pulp, and asbestos. In an example, urea is condensed with aqueous formaldehyde solution, with sodium carbonate, in the presence of flowers of sulphur, and then refluxed with an aqueous solution of urea. The resulting solution is filtered and mixed with ground wood pulp, the paste dried in vacuo and ground with sodium bisulphate, pigments, and plasticizers.
