Solutions of polybutadiene of average molecular weight between 10,000 and 80,000 (determined as described on page 660 of "Rubber Chemistry and Technology, July 1949") are extruded into solutions of sulphur dioxide to form filaments, ribbons and other shaped articles.

The solvent used may be benzene, toluene or an ether and it may contain an activator such as tetralin hydroperoxide. Suitable solvents for the sulphur dioxide include mixtures of ethanol and water or aromatic hydrocarbons, e.g. toluene. Specifications 663,645, [Group VIII], and 666,644 are referred to.ALSO:Solutions of polybutadiene of average molecular weight between 10,000 and 80,000 (determined as described on p. 660 of "Rubber Chemistry and Technology," July, 1949) are extruded into solutions of sulphur dioxide to form filaments, ribbons and other shaped articles.

91	A process for the preparation of reaction products of polydienes with sulphur dioxide	GB1624948	1948-06-16	GB659083A	1951-10-17
A solution of a polydiene is mixed with an unsaturated compound of low molecular weight, the mixture is activated with oxygen or an oxygen-releasing substance which, if it is not a hydroperoxide, must be applied together with an ether, and is then contacted with sulphur dioxide. "Polydiene" includes natural rubber and polymers and copolymers of conjugated dienes with 4 to 6 carbon atoms, containing a plurality of unsaturated carbon to carbon linkages and having a molecular weight of at least 5000. Specified are polymers of butadiene, methyl or dimethyl butadiene, or pentadiene, copolymers of mixtures of these compounds and with alkenes, e.g. isobutene. The unsaturated compounds of low molecular weight must have at least one unsaturated carbon-to-carbon linkage and a molecular weight under 5000, and may be polymerization products. Examples are butadiene, 1.5-hexadiene, allyl alcohol, chloride, acetate, capronate, isothiocyanate or oleate, o-diallyl phthalate or diallyl adipate. They may be substituted with halogens or polar groups such as OH, NH2, NH, CNO, CNS and NCS. Suitable activators are hydrogen peroxide, ethyl hydroperoxide, tert.-butyl hydroperoxide, peracetic acid, cyclohexene peroxide, methyl-cyclohexene peroxide, tetra- and deca-hydronaphthalene peroxides and octahydroanthracene peroxide. The sulphur dioxide is preferably employed in solution of which the solvent may be miscible with that for the polydiene. The reaction products may be obtained in the form of threads, fibres, bands or films by extruding the solution of polydiene and low molecular compound, containing a hydroperoxide, through a narrow orifice into a solution of sulphur dioxide in, e.g., ethyl alcohol, coagulation occurring immediately. Specifications 611,919 and 616,276 are referred to.ALSO:A solution of natural rubber is mixed with an unsaturated compound of molecular weight below 5000, the mixture is activated with oxygen or an oxygen-yielding substance which, if it is not a hydroperoxide, must be applied together with an ether, and is then contacted with sulphur dioxide.

94	A process for the manufacture of valuable reaction products of high-molecular unsaturated substances containing more than one unsaturated grouping in the molecule with inorganic acids or acid anhydrides	GB3245545	1945-11-30	GB611919A	1948-11-05
The reaction between polymers of average molecular weight above 5000 and containing a plurality of unsaturated carbon-to-carbon linkages and inorganic acids or acid anhydrides in the presence of aliphatic, cyclic or aliphatic-cyclic ethers is accelerated by first subjecting the mixture of unsaturated substance and ether to a slight oxidation by oxygen or an oxygen-yielding compound. Examples are polymers of dienes and their derivatives, polymers of acetylenes, copolymers of these with each other, copolymers of butadienes with vinyl acetylene, copolymers of dienes or acetylenes with isobutene, styrene, vinyl chloride, vinyl esters, acrylic and methacrylic acids, acrolein, methyl isopropenyl ketone and vinyl ethyl ether. The inorganic acids or anhydrides are those in which the acid forming elements are not present in their highest valency, e.g. sulphur dioxide, nitrogen trioxide, phosphorus trioxide, the corresponding acids or aqueous solutions, hydrogen sulphide, and hydrochloric and hydrobromic acids. Plasticizers, fillers, stabilizers and colouring matter may also be present. Examples of ethers are diethyl ether, di-isopropyl ether, pentamethylene oxide and dioxane. Oxygen-yielding substances include air, ozone, hydrogen peroxide, acetyl, benzoyl and tetrahydronaphthalene peroxides, persulphates, percarbonates and perborates. The oxidation, which may be effected by adding .1-1 per cent of the oxidizing compound to the polymer dissolved in the ether or in a mixture of the ether and benzene, should only proceed to the formation of peroxide-like compounds without other oxidation and decomposition products being formed. The invention may be applied to the manufacture of products such as filaments, tapes, films and foils when solutions of the high molecular substances are extruded into media, e.g. methyl or ethyl alcohol and greater reaction may be brought about by using mixtures, e.g. natural rubber and polybutadiene.ALSO:The reaction between high molecular unsaturated substances and inorganic acids or acid anhydrides in the presence of aliphatic, cyclic or aliphatic-cyclic ethers is accelerated by first subjecting the mixture of unsaturated substance and ether to a slight oxidation by oxygen or an oxygen-yielding compound.
