三嵌段共聚物大分子引发剂的合成

Synthesis of Macromolecular Initiator of Triblock Copolymer

首先用Novozyme 435作为催化剂合成了聚己内酯-聚乙二醇-聚己内酯三嵌段聚合物,然后通过端基官能化法合成了大分子引发剂。通过核磁表征了三嵌段聚合物和大分子引发剂的结构,从而制备含氟功能五嵌段共聚物,该聚合物在很多领域具有潜在的应用价值。

Polycaprolactone-polyethyleneglycol-polycaprolactone triblock copolymer which used Novozyme 435 as catalyst was synthesised.Then through the end functionalized the macroinitiator was synthesized.And characterization of triblock copolymer and macromolecular＇s structure through MRI,Fluorine-containing pentablock copolymer was synthesised which had potential application value in many areas.
