PCL-PEG-PCL 共聚物
PEG-PCL 嵌段共聚物
Biotin-PEG-PCL 生物素聚乙二醇聚己内酯
PEG-b-PCL-b-PEG 两亲性三嵌段共聚物
At present, block copolymers containing PCL and PEG chains are mainly prepared by active ionic polymerization using traditional chemical catalysts, some toxic organometallic compounds.
然而，两亲嵌段共聚物的传统的制备方法是有机金属催化剂催化的活性离子聚合法，故产物中难免会残留有毒的有机金属催化剂。
