The thermal copolymerization of styrene and acrylonitrile in the presence of inorganic salts like SJCl2, CdCl2, MnCl2 and NiCI2 Was invesdpted. The dereuing effects of thele salts on the rate was observed. The initiation reaction takes place thermally by the adsorption of the reacting monomers on the solid lUIface of inoIpDic: salts. The addition of salt doemot appreciably change the reactivity ratio values of the monomer. The lo'wering of molecular weight suggests that salts behave as a chain transfer agents.
