| Abstract
| - The chain-transfer constants of methyl (2-bromomethyl)acrylate (MBrMA) in bulk polymerizations of methyl methacrylate (MMA) and styrene were determined at 70 °C using both the Mayomethod (1/DPn as well as 2/DPw) and the chain-length-distribution procedure (Λ). The CMBrMA valuesusing 2/DPw and Λ were consistent, i.e., 1.28 and 1.20 for MMA and 11.44 and 10.92 for styrene,respectively. MBrMA was used as a chain-transfer agent in the emulsion polymerization of MMA to yieldan α-bromo-functionalized macromonomeric latex (〈Mn〉 = 9.6 × 103 g mol-1; PDI = 1.80), which wassubsequently copolymerized with styrene to yield the corresponding poly(styrene-graft-MMA) copolymer.MBrMA was used as an addition−fragmentation agent in the living radical polymerization of MMAmediated by copper(I) bromide/N-(n-octyl)-2-pyridylmethanimine. In situ addition of a 5-fold equivalentof MBrMA and Cu(0) to this polymerization quenched the reaction and transformed the ω-bromide intothe methacrylate-based macromonomer quantitatively.
