The thermal copolymerization of acrylonitrile and allyl alcohol in the presence of oomplexing agents like HgCI2, erCI3, ZnCI2 and CdCI2 is investigated. Accelerating effects of com­plexing agents were observed. The complexation in the case of AN takes place through nitrile group whereas in the case of ·allyl alcohol the complex formation occurs on allylic group. of the monomer. The inorganic salts act as chain transfer agent and do not appreciably change the reactivity ratios values of the monomers. The copolymerization mechanisam is also discussed.
