摘　　要：本文以乳酸(LA)、丙炔醇乙氧基醚(PME)为原料,通过直接熔融聚合法合成了一系列不同投料比的含末端炔基的聚乳酸高分子(PLA-PME),并用IR、^(1)HNMR、DSC、XRD等分析手段,对不同投料比的PLA-PME产物进行结构与性能表征。结果表明,通过直接熔融聚合法可以将末端炔基引入到PLA链段中。该方法有望进一步通过Click Chemistry反应将三氮唑药物因子引入到PLA链段中,扩展了聚乳酸高分子的应用领域。A series of polylactic acid polymers(PLA-PME)with different feed ratios were synthesized by direct melt polymerization with lactic acid(LA)and propylene glycol(PME)as raw materials,The chemical structure and properties of PLA-PMEs with different ratios were characterized by IR,^(1)H NMR,DSC,XRD.The results were shown that alkynyl was indeed introduced into PLA chains.This method could be used for introduction of triazole-based drug into PLA materials by Click Chemistry reaction.Furthermore it will be expended the application of PLA polymer.
