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-polybutadienyl polyurethane was prepared by coupling poly (L-lactic acid) with hydroxy-terminated polybutadiene in the molten state with diphenylmethane-1,4-diisocyanate. The structure and properties Analytical characterization. The results showed that the introduction of polybutadiene improved the brittleness of PLA.
