Abstract
A monovinyl aromatic hydrocarbon and/or its ar-halo derivative is polymerized by heating and increasing the temperature towards the end of the polymerization so that the last part only of the polymerization is at 180-220 DEG C., at least the last part of the polymerization is effected in the presence of a catalyst which is an organoperoxysilane, other than t-butylperoxytrimethyl silane, having a half-life of 220-30,000 hours in benzene at 100 DEG C. The monomer may be styrene p-chlorostyrene, or o-, m- and p-methylstyrene with optionally a -methylstyrene, methyl methacrylate or acrylonitrile, and may contain a dissolved rubbery conjugated 1,3-diene polymer, e.g. a butadienestyrene copolymer. The silane may be a di- or tri-(t-butylperoxy) di- or mono-methyl silane, tetra (t-butylperoxy) silane, di (t-butylperoxy) methylphenylsilane or tri (t – butylperoxy) phenyl silane. The monomers and catalyst may be heated at 75-125 DEG C. until 15-45% conversion to polymer is obtained and the temperature is then raised to 180-200 DEG C. over a period of 3-7 hours and maintained for 1/2 -5 hours. The catalyst may also comprise hydrogen peroxide and di-t-butyl peroxide. In comparative examples styrene is polymerized by heat alone and using di-t-butyl peroxide alone.
