摘要: 研究了聚乳酸(PLA)与氨基酯类弹性体共混材料的冷结晶性能,探讨了氨基酯类弹性体含量及升温速率对PLA结晶速率和结晶度的影响。结果表明,氨基酯类弹性体可诱导PLA的结晶,加快其结晶过程。随着氨基酯类弹性体含量的增加,PLA的结晶速率降低,结晶度下降;且升温速率越快,PLA越难结晶。

Abstract: The cold crystallization properties of the blends of poly(lactic acid) (PLA) and amino-ester elastomer were studied. It was found that the amino-ester elastomer promoted the crystallization of PLA. The crystallization rate and crytallinity of the blends decreased with increasing content of amino-ester elastomer and also with increasing heating rate.

Key words: poly(lactic acid), amino ester elastomer, blending, crystallization behavior
