Zusammenfassung:A process for preparing chlorinated polyolefin and polydiolefin compounds which includes a step during which a polyisoprene latex is treated with gaseous chlorine in the presence of hydrochloric acid, of ultraviolet radiation and of an agent that promotes chlorination and relative molecular mass reduction. The promoting agent is hydrogen peroxide and is contained in the reaction medium in the amount of 0.5% to 10% by weight with respect to the weight of the polyisoprene.
