Exceptional free radical polymerization and block copolymerization of captodative substituted methyl 2-methoxyacrylate

Abstract

Free radical polymerization of captodative substituted methyl 2-methoxyacrylate (MMOA) was carried out in bulk with or without azo initiators at 90-130°C. At higher temperatures, bimodal molecular weight distribution polymer was obtained by the polymerization of MMOA irrespective of the presence of initiator in contrast to the polymerization at 90°C where unimodal polymer was produced. In addition, block copolymers were conveniently obtained by heating the comonomers including vinyl acetate and acrylonitrile at 130°C in the presence of poly(MMOA) without any initiator. These unique reactions were reasonably explained by the cleavage of captodative substituted carbon-carbon single bond at head-to-head structure in polymer chain, which was produced by recombination termination.
