Abstract

Graft polymers are prepared by treating with a polymerization catalyst anaqueous dispersion of a polymer or copolymer obtained by the emulsion polymerization of a vinyl compound such that active centres are induced in the trunk of the polymer, and then introducing an additionpolymerisable monomer which graft polymerizes directly on to the active centres to form branches. Polymers specified are those of ethylene, propylene, styrene, butadiene, isoprene, vinyl and vinylidene chlorides, vinyl acetate, acrylonitrile and methyl methacrylate and copolymers thereof, e.g. styrene-butadiene and styrene-butadiene-divinyl benzene copolymers. Monomers specified are styrene, butadiene, acrylonitrile, methyl methacrylate, vinyl chloride and vinyl acetate. Polymerization catalysts specified are potassium persulphate, tert. butyl peracetate and tert. butyl hydroperoxide. The aqueous polymerization medium may contain a dispersing agent. In an Example (6) a graft polymer obtained by polymerizing a mixture of styrene and butadiene on to a styrene-butadiene copolymer is mixed with natural rubber, aluminium silicate and conventional vulcanizing recipe ingredients and then vulcanized. Specification 847,603 is referred to.
