摘要
利用搅拌反应釜合成了乙交酯和L-丙交酯的共聚物PGLA(90/10),并用自制的纺丝机对聚合物进行纺丝,得到PGLA(90/10)纤维。研究了聚合过程中特性黏度、单体转化率等的变化规律,应用IR、1H-NMR、DSC、TG、毛细管流变仪等对聚合物的结构、热性能、流变性能进行了表征。
Poly (glycolide-lactide) was synthesized by copolymerization of glycolide (GA) and L-lactide (LA) (GA/LA=90/10 in mol) in the stirred-tank reactor, then PGLA (90/10) fibers were obtained by melt spinning. The influences of polymerization time on the polymerization were studied in detail. The structure and properties of PGLA(90/10) were analyzed by IR, ^1H-NMR, DSC, TGA, capillary rheogeniometer.
