甲基丙烯酸 2-(二甲氨基)乙酯 (DMAEMA) 依次与其他三种甲基丙烯酸叔胺共聚单体通过基团转移聚合进行嵌段共聚；在温和条件下使用丙烷-1,3-磺内酯选择性甜菜碱化这些二嵌段共聚物的DMAEMA残基，产生一系列新型水溶性磺基甜菜碱嵌段共聚物，其表现出可逆的pi-I-和温度诱导的胶束化。
2-(Dimethylamino)ethyl methacrylate (DMAEMA) was block copolymerised in turn with three other tertiary amine methacrylate comonomers using group transfer polymerisation; the DMAEMA residues of each of these diblock copolymers were selectively betainised using propane-1,3-sultone under mild conditions to yield a series of novel water-soluble sulfobetaine block copolymers which exhibit reversible pi-I-and temperature-induced micellisation.
