Blends of vinyl chloride polymers and chlorination products of polyolefins well suitable for dry blend technique are obtained by using a chlorinated low pressure polyethylene with a chlorine content of 38 to 42% by weight, a residue value of 55 to 70% by weight and a swelling value of less than 1% by weight, prepared from high-density polyethylene, having a density of 0.955 to 0.965 g/cm.sup.3, a melting index of 20 to 65 g/10 min and a reduced specific viscosity of 1 to 2 dl/g, under certain conditions.

DETAILED DESCRIPTION What is claimed is: 1.
Thermoplastic composition consisting of (a) 95 to 70% by weight of a vinyl chloride polymer and (b) 5 to 30% by weight of a chlorinated high-density polyethylene, wherein the chlorinated high-density polyethylene has a chlorine content of 38 to 42% by weight, a residue value of 55 to 70% by weight (determined by extraction with toluene/acetone in a ratio of 1:1) and a swelling value of less than 1% by weight (measured in methyl-cyclohexane) and has been prepared from high-density polyethylene having a density of 0.
