Abstract
Polymerisations of methyl methacrylate, styrene or N-isopropyl acrylamide in the presence of 1-phenyl(trimethylsiloxy)ethylene (1) generate telechelic oligomers with end groups derived from initiator fragments and termination by radical alkylation of 1. Inclusion of a difunctional monomer produces highly branched polymers that are free from gel.
摘要
在 1-苯基(三甲基硅氧基)乙烯（1）存在下聚合甲基丙烯酸甲酯、苯乙烯或 N-异丙基丙烯酰胺，会生成端基来自引发剂片段的遥爪低聚物，并通过 1 的自由基烷基化终止。加入双官能单体可生成无凝胶的高度支化聚合物。
