Abstract
A rubber-like product is obtained by treating a mixture of butadiene, or an alkyl, aryl, or chlorsubstitution product thereof, and a vinyl ethinyl carbinol. Specified ingredients are butadiene, isoprene, 2.3-dimethylbutadiene, 2-phenylbutadiene, monochlor- and dichlor-butadienes, vinyl ethinyl dimethyl carbinol, 1-vinyl-ethinyl-cyclohexane-1-ol, vinyl ethinyl ethyl methyl carbinol and vinyl ethinyl-di-isopropyl carbinol. The polymerization may be carried out by heating the mixture of the monomers in the presence of per-compounds, and if desired under pressure, or in aqueous emulsion. The interpolymers are practically insoluble in organic solvents, may be mixed with fillers or dyestuffs, and may be vulcanized, after the addition of vulcanizing agents, vulcanization accelerators and, if desired, agents protecting against ageing, to form articles similar to soft or hard rubber. In examples: (1) butadiene and vinyl ethinyl dimethyl carbinol are heated in a closed vessel in the presence of benzoyl peroxide; (2) beta-chlorbutadiene and vinyl ethinyl dimethyl carbinol are heated in a closed vessel with benzoyl peroxide; the interpolymer produced is mixed with colophony, a softener obtained by extracting lignite low temperature carbonization tar with ethyl alcohol, gas carbon, zinc oxide, magnesium oxide, sulphur and N-phenyl-, beta-naphthylamine and treated to form a product resembling hard or soft rubber depending upon the proportions of the ingredients used to form the interpolymer; (3) beta-chlorbutadiene and vinyl ethinyl dimethyl carbinol are emulsified with water, ammonia, oleic acid and benzoyl peroxide, and the emulsion heated; the interpolymer is heated in the mixture described in example 2 to yield a product similar to hard rubber; (4) beta-chlorbutadiene and 1-vinyl-ethinyl-cyclohexane-1-ol are heated in a closed vessel with benzoyl peroxide; and (5) butadiene and vinyl ethinyl dimethyl carbinol are emulsified with an aqueous solution of sodium oleate, ammonium persulphate is added, and the mixture heated in a closed vessel; a small amount of phenyl beta-naphthyl amine dissolved in benzene or dispersed in water is then added and the interpolymer coagulated by the addition of sodium chloride and acetic acid.
