Abstract

Copolymers are made by bulk polymerizing at temperatures between 80 DEG and 200 DEG C. a mixture of from 20 to 40 per cent of acrylonitrile and from 80 to 60 per cent of styrene and/or alpha-methyl styrene in the presence, as a stabilizer, of from 0.1 to 1 per cent of oxalic, glyoxylic or formic acid, the polymerization being conducted at least for a substantial part of the time at temperature above 120 DEG C. A small proportion of unsaturated dimers of alpha-methyl styrene may also be present during polymerization.
