STUDY OF RADICAL COPOLYMERIZATION OF 4-CHLORO-3-NITROSTYRENE WITH VINYL MONOMERS

Results of the copolymerization of 4-chloro-3-nitrostyrene (4-CNS) wit h acrylic and vinylic monomers in bulk or in solution are reported tog ether with some related physico-chemical characterizations, i.r. and n .m.r. data, d.s.c., and solubility properties. These experiments allow ed us to characterize the high reactivity of 4-CNS and its main effect s (inhibition or retardation) on the copolymerizations studied. In all cases, and more particularly with methacrylic derivatives, copolymeri zation proceeded slowly, and at limited conversion rates; the copolyme r compositions reveal preferential incorporation of 4-CNS. For methyl methacrylate copolymerization no significant induction time was detect ed, indicating a retarding effect on the kinetics due to 4-CNS. (C) 19 97 Elsevier Science Ltd.
