摘要
用液化改性MDI、丁羟胶(HTPB)和端羟基聚乳酸(PLA OH)为原料,合成一系列不同结构的聚氨酯弹性体,并对这些聚合物进行了红外结构、力学性能、热稳定性的研究,初步探讨了其在37℃KH2PO4 Na2HPO4缓冲溶液(pH=7.0)中的降解性能。
Using liquefaction modified MDI,HTPB and PLA-OH as raw materials,A series of polyurethane elastomer with different composition were synthesized,and the structure,mechanical properties and thermal stability were studied.The degradable behaviors of the elastomer in the phosphate buffer solution were investigated as well.
