Compositions comprise (A) 100 parts by weight of a vinyl chloride polymer; (B) 1 to 15 parts by weight of a polybutadiene-1,3 having 20 to 80 mole per cent of 1,4-cis units; and (C) 3 to 50 parts by weight per 100 of the sum of (A) and (B) of an interpolymer of acrylonitrile, butadiene and styrene. The vinyl chloride polymer may be polyvinyl chloride or a vinyl chloride/vinyl acetate copolymer. The compositions may also comprise stabilizers, e.g. lead stearate and cadmium stearate, and lubricants, e.g. butyl stearate, and may be used for making articles by injection moulding and extrusion. |
