    Abstract: 1,231,634. Chlorinating polyolefins. BADISCHE ANILIN- & SODA-FABRIK A.G. 13 Sept., 1968 [16 Sept., 1967], No. 43658/68. Heading C3P. A chlorinated polyolefin is produced by the action of chlorine on a polyolefin in the presence of chlorohydrocarbon in a continuous process wherein a particulate polyolefin, a chlorohydrocarbon and chlorine are continuously introduced into a reaction zone which contains a reaction mixture of polyolefin, chlorinated polyolefin which is partly dissolved in the chlorohydrocarbon and chlorine, a solution of chlorinated polyolefin and chlorine in the chlorohydrocarbon is withdrawn from the reaction zone at a rate corresponding to that at which the polyolefin, chlorohydrocarbon and chlorine are continuously introduced, a major proportion of the chlorine and some of the chlorohydrocarbon are distilled off from the solution and the solution is introduced into boiling water, the chlorohydrocarbon is distilled off and then the aqueous phase is separated from the chlorinated polyolefin. The term " polyolefin " includes not only homopolymers of olefins but also copolymers of two or more olefins. Suitable chlorohydrocarbons are carbon tetrachloride, chloroform and trichloroethane.
