聚环氧乙烷-聚丙交酯嵌段共聚物的合成
The Synthesis of Block Copolymer mPEO-b-PLA
摘要
Abstract
The poly( ethylene oxide) (mPEO) was polymerized with ring-opening polymerization of ethylene oxide with living anionic polymerization using self-made diethylene glycol monomethyl ether potassium as initiator. Its molecular weight is 2 000, molecular weight distribution 1.07, one end is methoxy, and the other hydroxyl. Then, mPEO was served as macroinitiator to initiate the polymerization of D, L-lactide by coordinationinsertion ring-opening polymerization using stannous octoate ( Sn (Oct)2 ) as catalyst, and the amphiphilic block copolymers mPEO-b-PLA were obtained. The molecular weights are 5 250,14 070,23 360,44 300 and molecular weight distribution 1.45,1.47,1.53,1.59 respectively. The final product and intermediate product were characterized by 1H-NMR and GPC in detail. The polymerization is controllable.关键词
