- Abstract
Poly(methyl methacrylate)s (PMMA)s and poly(methyl acrylate)s (PMA)s are prepared by atom transfer radical polymerization (ATRP) or single electron transfer-living radical polymerization (SET-LRP) using methyl dichloroacetate (MDCA) and ethyl dibromoacetate (EDBA) as bifunctional initiators. The chain-end functionality is determined by MALDI-TOF mass spectrometry. The target PMMA ( Mn = 2000 g mol−1) and PMA ( Mn = 2000 g mol−1) samples obtained by ATRP of MMA and MA with MDCA as initiator have 12 and 81 mol% bis-chloro end groups, respectively; those prepared by SET-LRP have 57 and 100 mol% bis-chloro end groups, respectively. The PMMAs obtained by ATRP or SET-LRP with EDBA have no bromine end groups.
