1,183,806. Chlorinated P.V.C. compositions. WACKER-CHEMIE G.m.b.H. 13 Jan., 1969 [12 Jan., 1968], No. 1850/69. Headings C3G and C3P. Moulding compositions comprise (a) chlorinated P.V.C., (b) 5-25% based on the weight of (a) of a copolymer of butadiene, styrene and either acrylonitrile or a methacrylic ester and (c) 0À1-5% by weight of the composition of a high density polyethylene having a molecular weight of 20,000-200,000. The copolymer (b) is preferably a graft polymer; commercial products are used in the examples. Also present are a lead stabilizer and a fatty alcohol lubricant.
