【摘要】 采用原位乳液聚合方法制备聚甲基丙烯酸甲酯（PMMA）包覆TiO₂（TiO₂/PMMA）,发现纳米TiO₂对甲基丙烯酸甲酯的聚合无阻聚作用。研究表明:PMMA包覆在纳米TiO₂表面主要为物理包覆,有少量化学包覆。在丙烯酸涂料中,TiO₂/PMMA比TiO₂更易分散。用TiO₂/PMMA制得的涂料流平性好,涂膜性能优良。更多还原

【Abstract】 This article has described the in situ emulsion polymerization of nano - scale TiO2 encapsulated with polymethyl methacrylate (TiO2/ PMMA), and found that the nano - scale TiO2 shows no effect on inhibition of polymerization of MMA. It has shown that the main part of PMMA was encapsulated on TiO2 physically, only a few was encapsulated chemically. The TiO2/ PMMA is more easily dispersed in acrylic paint system than TiO2. The paint shows better leveling property and excellent film performance.更多还原
