Abstract

In a process for the sulphochlorination of polymers containing chlorine, the polymers are reacted with thiourea in order to transform them into polymer isothiouronium salts and the salts are subjected to the action of chlorine in an aqueous medium. Specified chlorinated polymers are polyvinyl chloride, polyvinylidene chloride, polychlorostyrenes, polychlorobutadienes, chlorinated polyethylene, chlorinated polypropylene, chlorinated copolymers of olefins, chlorinated rubbers and hydrochlorinated rubbers. N-methyllated thioureas, e.g. tetramethyl thiourea may be used in place of thiourea, and the formation of the salt effected in solution or suspension, e.g. in butyl alcohol, isooctyl alcohol, 2-ethylhexyl alcohol, cyclohexanol, cyclohexanone, decalin, carbon tetrachloride, tetrachlorethane and water. U.S.A. Specifications 2,212,786 and 2,405,971 are referred to.
