摘　　要：针对聚乳酸结晶速度慢、结晶度低的问题,通过添加聚乳酸成核剂TMC-300来改善其结晶性能。实验过程采用热重、红外、结晶速率测定仪以及X光衍射等手段考察了成核剂TMC-300对聚乳酸结晶的影响。成核剂TMC-300没有对聚乳酸的结构和晶型造成影响,但大大缩短了半晶时间。在0.8%的添加量下,半晶时间低至40 s。结果表明,TMC-300是一种有效的聚乳酸成核剂。In order to solve the problem of slow crystallization rate and low crystallization,the nucleating agent TMC-300 was used into PLA.Crystallization behavior of poly（lactic acid） was examined by using TG,IR,Crystallization tester and XRD.TMC-300 did not affect the structure and crystalline of polylactic acid,but greatly reduced the crystallization half-time.The crystallization half-time was up to 40 s at the amount of 0.8％.It was showed that TMC-300 was an effective nucleating agent of polylactic acid.
