Abstract

Graft polymers are made by polymerizing a monovinyl aromatic compound, e.g. styrene, or a mixture thereof with acrylonitrile, methyl methacrylate and/or alpha-methyl styrene, in the presence of a block copolymer prepared from a conjugated diolefine and a monovinyl aromatic monomer, preferably a butadienestyrene block copolymer. The grafting reaction is preferably carried out either by bulk polymerizing the monomer-polymer mixture in a first stage, followed by polymerization in aqueous suspension in a second stage, or by polymerizing a monomer-polymer mixture containing 3 to 30% of ethyl benzene. Also present during polymerization may be perioxide catalysts, e.g. tert.-butyl perbenzoate and benzoyl peroxide.
