The thermal copolymerization of styrene and allyl alcohol in the presence of salts like SrC12, HgC12, CdCl2. ZnCI2, PtCl6 and NiCI2 without using any radical initiator is investigated. The salts increased the rate of copolymerizatio,.. It is due to complex formation of inorganic salts with allyl alcohol which occurs on allylic group of the monomer. The inorganic salts act as chain transfer agent and do not appreciably change the reactivity ratios of the monomers. The copolymerization mechanism is also discussed.
