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。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.
