Abstract: Styrene is polymerixzed with optionally up to 45% by w. of acrylonitrile a - or nuclear-methyl styrene, and mono- or di-chlorostyrene, at 80-180 DEG C., the polymerization being carried on until the coversion if 45-95% and the remaining monomers and any diluent being removed by degassing in vacuo, and prior to degassing there is added to the polymerization mixture, before or during polymerization, 0.1-5% of an ester of a dimer or trimer of a fatty acid which is oleic, linoleic, linolenic or elaidic acid, with a C1- 18 alcohol and/or an ester of a C18 acid with an alconol which has been obtained by hydrogenation of the above dimer or trimer and/or an alcohol which h as been obtained by hydrogenation of the above dimer or trimer. the polymerization may be carried out in the presence of up to 50% of diluent e.g. ethylbenzene. The ester may be te butyl or ethylhexyl ester of the fatty acid. The polymerization may be continuous. The styrene may be polymerized in the presence of a rubber comprising 25% styrene and 75% butadiene.
