Abstract
Allyl bromide as well as methyl α-(bromomethyl)acrylate functioned as an effective chain transfer agent through addition-fragmentation reaction in the radical polymerization of methyl methacrylate and methyl acrylate. The 1H NMR spectra of the polymers revealed that the end groups of the polymer with the controlled molecular weight arise from addition of the polymer radical to the carbon-carbon double bond of the transfer agent accompanying subsequent scission of the carbon-bromine bond and reinitiation with bromine atom. However, allyl bromide was found to be almost ineffective in styrene polymerization, because of a low reactivity of the carbon-carbon double bond toward poly(styrene) radical.
