| 摘 要： | 对采用种子乳液聚合法合成的包覆Fe2O3超微粒的苯乙烯/丙烯酸/丙烯酸丁酯(St/AA/BA)核-壳型复合共聚物材料进行玻璃化温度测试,结果表明,加入Fe2O3超微粒,使复合共聚物的玻璃化温度显著降低.对复合共聚物的流变行为研究表明,复合共聚物的非牛顿指数均小于1,且随着Fe2O3含量增加,非牛顿性增强,表观粘度下降,粘流活化能降低.

| Abstract: | Fe2O3 nanoparticles were encapsulated in the core-shell composite copolymers of St/AA/BA (styrene/acrylic acid/butyl acrylate) by seed emulsion polymerization process.The influence of Fe2O3 on rheological behavior and glass transition temperature (Tg) of St/AA/BA core-shell composite copolymer was discussed. The result of DSC showed that the addition of Fe2O3 nanoparticles could decrease Tg for the composite copolymer. According to the rheological properties, the core-shell copolymers were all pseudoplastics and their nonNewtonian index was less than 1. The viscosity and △E decrease with the increase of the Fe2O3 content. |
