Abstract: A composition comprises (i) from 0.5 to 25 parts by weight of an after-chlorinated polyethylene having a relative viscosity of of 1.5 to 18 and a chlorine content of from 20 to 60% by weight, and (ii) from 99.5 to 75 parts by weight of an after-chlorinated stereoregular polyvinylchloride having a relative viscosity of 1.5 to 6.5 and a chlorine content of from 58 to 71% by weight, the chlorine atoms of the after-chlorinated polyvinyl chloride originally being 55 to 85% syndiotactically arranged. Other components of the composition may be: polyvinyl acetate, polyethylene, polyacrylonitrile, lubricants, e.g. low molecular weight polyethylene or barium cadmium stearate, stabilizers, pigments, dyestuffs, fillers, and light-protection agents, e.g. phosphorous acid esters. The chlorination of polyvinyl chloride in suspension, using a swelling agent, excess chlorine, and ultra-violet light, is described in the examples. In comparative Examples 5-8, an after-chlorinated atactic polyvinyl chloride is used in place of the stereoregular polymer. The compositions may be formed into shaped elements or coatings.
