摘　　要：通过考察市售的成核剂品种TMC-328与TMC-300对聚乳酸结晶的影响发现,这两种成核剂对聚乳酸结晶均有促进作用,对聚乳酸的抗冲击性也均有提高。Poly（lactic acid） is a biobased and compostable thermoplastic polyester that has rapidly evolved into a competitive commodity material over the last decade.PLA boasts a high modulus,high strength and good clarity.Therefore,one key bottleneck in extending the use of PLA is the control of its crystallinity.Nucleating agent has played an important role with the development of PLA.Influence of two commercial nucleating agent TMC-328 and TMC-300 on PLA crystallization was investigated in this paper.It was showed that both nucleating agents promote crystallization of PLA while increases its impact strength.
