Abstract
Chlorinated polyvinylchloride is obtained by chlorinating under anhydrous conditions a powdery mixture of a polyvinylchloride and a minor quantity of a chloroalkane. The polymer may be a homopolymer or a copolymer with vinyl acetate or propylene obtained by suspension polymerization having a viscosity in cyclohexanone of 0À3-0À75 and a particle size of 50- 150 microns. Chlorination is effected with chlorine photochemically or in the presence of a radical catalyst which may be dissolved in the chloroalkane. Chloroform, carbon tetrachloride and 1,2-dichloroethane are mentioned used in amounts of 10-55 parts per 100 parts of polymer, and removed afterwards by distillation.
