摘要: 用分步溶液聚合法合成了两种丙烯酸酯共聚物的共混物[P(BA-HEMA-AA)/P(MMA-HEMA-AA)A],制成无皂水溶胶,加入交联剂配成涂料。两种共聚物既可相互贯穿缠结,又可通过交联剂交联,使涂膜同时具有物理交联和化学交联。用动态力学分析法(DMA)、扭辫分析法(TBA)考察了涂膜的动态力学性能,表明涂膜具有IPN结构,并有良好的阻尼性能。Abstract: new kind of soap-free water-solubilized polyacrylic colloidal dispersions composed of two copolymers (P (BA-HEMA-AA)/P(MMA-HEMA-AA) has been prepared by the sequential solution polymerization method. The coating can be obtained by adding the cross-linking
