摘要： 在三异丁基铝催化下DL-丙交酯与2-氢-2-氧-1,3,2-二氧磷杂环己烷开环共聚,制备了一类新型水溶性共聚物P(LA-co-TMP).用1HNMR、IR谱对其结构进行了表征,并研究了催化剂用量及不同单体配比对总转化率、共聚物组成及特性粘度的影响.

Abstract: A new kind of water-soluble copolymers were prepared by ring-opening copolymerization of DL-lactide and 2-hydro-2-oxo-1,3,2-dioxaphosphorinane,using triisobutylaluminium as the initiator. The final copolymers were characterized by 1HNMR,IR spectrometry.The influences of the amounts of initiator and molar ratio of the monomers on the total conversion,monomer conversion,copolymer composition,intrinsic viscosity of the copolymers were investigated,respectively.

Key words: DL-Lactide, 2-Hydro-2-oxo-1,3,2-dioxaphosphorinane, Ring-opening copolymerization
