Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>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 (<italic>M</italic>_n = 2000 g mol⁻¹) and PMA (<italic>M</italic>_n = 2000 g mol⁻¹) samples obtained by ATRP of MMA and MA with MDCA as initiator have 12 and 81 mol% <italic>bis</italic>‐chloro end groups, respectively; those prepared by SET‐LRP have 57 and 100 mol% <italic>bis</italic>‐chloro end groups, respectively. The PMMAs obtained by ATRP or SET‐LRP with EDBA have no bromine end groups. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2h35qk6q" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
