Beschreibung
Zusammenfassung:	A composition of a vinyl chloride polymer or copolymer containing more than 50% vinyl chloride and a chlorinated polyolefin having a chlorine content of 20-50% and which has been obtained by chlorinating a polyolefin having a reduced viscosity of not less than 0,5 determined in a 0,5% solution of the polyolefin in tetrahydronaphthalene at 120 DEG C. in the presence of water at above 90 DEG C. Comonomers specified are vinyl acetate, propionate, butyrate, stearate, vinylidene chloride and acrylic, methacrylic and maleic alkyl esters. While low pressure polyethylene and ethylenepropylene copolymer are the specified polyolefins. Specification 828,938 is referred to.
