以乙氧基乙基缩水甘油醚（EEGE）为单体，3-苯基-1-丙醇和双季戊四醇为引发剂，分别合成了线型和星形聚缩水甘油。这些聚合物用2-氯乙基磺酰氯处理以形成反应性乙烯基磺酸酯端基。研究了乙烯基磺酸酯端基对胺、醇和氨基酸的高反应性。所有的聚合物，其特征在于通过核磁共振和尺寸排阻色谱。
Linear and star-shaped polyglycidols were prepared using ethoxy ethyl glycidyl ether (EEGE) as monomer and 3-phenyl-1-propanol and dipentaerythritol as initiator, respectively. These polymers were treated with 2-chloroethylsulfonyl chloride to form reactive vinyl sulfonate end groups. The high reactivity of the vinyl sulfonate end groups toward amines, alcohols, and amino acids was investigated. All polymers were characterized by nuclear magnetic resonance and size exclusion chromatography.
