摘要： 以醋酸酐封端的不饱和聚酯(FUPR)与交联聚氨酯预聚物制备了具有互穿聚合物网络(IPN)的不饱和聚酯/聚氨酯,通过红外,DSC和扫描电镜等分析了FUPR/PUIPN网络形成的动力学,微相分离行为及力学性能.结果表明,当FUPR/PU达到其一比值时,产生网络互穿效应,可改善聚氨酯的刚性,提高不饱和聚酯的抗冲性.

关键词: 互穿聚合物网络, 不饱和聚酯, 聚氨酯, 合成

Abstract: A polyester/polyurethane interpenetrating polymer network(IPN)was prepared from acetoxy terminated unsaturated polyester(FUPR) and crosslinked polyurethaiie pre-polymer.The kinetics of network formation, behavior of rnicrophase separation and mecha-nical properties of the IPNs were examined by IR,DSC,and SEM. The results showed that the IPN was formed at a certain ratio of FUPR/PU.The products showed an improved ri-gidity to polyutrethane and increased impact strength to ui1saturated polyester.

Key words: interpenetrating polymer network, unsaturated polyester, polyurethane, synthesis
