Abstract

The cross-linking acrylic polymer latex based on methyl methacrylate, butyl acrylate, hydroxyethyl methacrylate, and hydroxyethyl acryloylurea was prepared by soap-free emulsion polymerization with sodium 2-acrylamido-2-methylpropanesulfonate and allyloxy alkyl polyoxyethylene ether ammonium sulfate (SR-10) used as the reactive emulsifiers. Glass transition temperature of the latex film prepared is 20°C. The average particle size of the latex is 64 nm and its dispersion index is 0.085. The optimum conditions of preparing the latex were found. In comparison with the conventional latex, the heat and water resistance of the resultant latex have been improved.

无皂乳液聚合法制备的交联聚丙烯酸酯胶乳的制备与表征

摘要以甲基丙烯酸甲酯、丙烯酸丁酯、甲基丙烯酸羟乙酯和丙烯酰脲羟乙酯为基础，以 2-丙烯酰胺基-2-甲基丙磺酸钠和烯丙基烷基聚氧乙烯醚硫酸铵（SR-10）为活性乳化剂，通过无皂乳液聚合法制备了交联丙烯酸聚合物胶乳。制备的胶乳薄膜的玻璃化温度为 20°C。胶乳的平均粒径为 64 nm，分散指数为 0.085。找到了制备胶乳的最佳条件。与传统胶乳相比，所制备胶乳的耐热性和耐水性均有所提高。
