摘要
以聚L-乳酸与端羟基聚丁二烯在熔融状态下用二苯甲烷-1,4-二异氰酸酯偶联制备了聚L-乳酸-聚丁二烯基聚氨酯,且对聚合产物结构和性能进行分析表征。结果表明:聚丁二烯的引入改善了聚乳酸的脆性。
Poly（L-lactic acid） （PLLA） is a biodegradable aliphatic polyester and primarily used for biomedical field. As an attractive alternative to traditional commodity plastics, the broad application of PLLA is mainly limited by the higher production cost and its brittleness under impact loads . To improve the properties of PLLA and expand its applications,
