戊二酸锌催化环氧丙烷与马来酸酐开环共聚反应

摘要

The ring‐opening copolymerization of propylene epoxide and cyclic anhydrides in the absence of solvent was conducted with zinc glutarate as the catalyst .The polymerization condi‐tions were optimized .The structure of as‐synthesized copolymer was characterized by infrared spectrometry and nuclear magnetic resonance spectroscopy (NMR) ,while its molecular weight was determined by gel permeation chromatography .Results show that zinc glutarate can effi‐ciently catalyze the ring‐opening copolymerization of propylene epoxide and cyclic anhydrides affording target copolymer with a high degree of alternation in a high yield .%以戊二酸锌为催化剂，在无溶剂条件下催化环氧丙烷与马来酸酐的开环共聚反应；优化了聚合条件，利用红外光谱和核磁共振谱研究了共聚物的结构，利用凝胶渗透色谱测定了其分子量。结果表明，戊二酸锌可以有效地催化马来酸酐与环氧丙烷的开环共聚，从而以较高转化率得到交替度较高的共聚物。
