摘　　要：本文介绍了离子型聚氨酯（ＩＰＵ）与聚丙烯酸酯（ＰＡ）胶乳互穿聚合物网络（ＬＩＰＮ）合成的原理和穿梭聚合工艺。研究了影响胶乳稳定性的因素；通过透射电镜的观察，证明胶乳粒子为核壳结构；用示差扫描量仪对其相容性进行研究，互穿聚合增进了聚氨酯和聚丙烯酸酯两种聚合物间的相容性；对ＬＩＰＮ成膜物物理机械性能的测试表明：穿梭共聚物获得了两种聚合物的折衷性能。This paper introduces the synthetic principle and technology of ionic polyurethane(IPU)/polyacrylate(PA)latex interpenetrating polymer networks(LIPN).The factors affecting the stability of IPU/PA LIPN emulsion are studied here. The nuclear-hull structure of the latex particles can be proved by means of SEM. And it can be proved by DSC that the compatibility of IPU and PA will be improved by interpenetrating polymerigation. Tests of the physical-mechanical property of its film show that the IPU/PA LIPN membrane have the comprehesive property.
