Abstract

1,231,130. P.V.C. compositions. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 5 Dec., 1969, No. 59509/69. Heading C3P. Powdered P.V.C. is mixed with pellets of ethylene/vinyl ester copolymer in a high speed mixer at a temperature above 130‹ C. at which the P.V.C. remains powdery. Preferably other constituents are mixed with the P.V.C. before the copolymer is added. In the examples such materials are tribasic lead sulphate, dibasic lead stearate, calcium stearate and glycerol monostearate. The copolymer added is ethylene/ vinyl acetate.
