摘　　要：以八甲基环四硅氧烷、乙烯基三甲氧基硅烷、丙烯酸丁酯、甲基丙烯酸甲酯、丙烯酸等为原料 ,采用种子乳液聚合法合成了高有机硅含量的有机硅 /丙烯酸酯接枝共聚物。利用红外光谱表征了有机硅丙烯酸酯共聚物的结构 ,利用热重分析测试了共聚物的热分解温度。结果表明 ,丙烯酸酯聚合物上成功地引入了有机硅链节 。The silicone/acrylate grafting copolymer containing high organosilicon was synthesized by seeded emulsion polymerization, taking octamethylcyclotetrasiloxane, vinyltrimethoxysilane, butyl acrylate, methyl methacrylate and acrylic acid as materials. FT spectrum characterized the structure of silicone-acrylate copolymer, while TG spectra testified heat resistance of the silicone-acrylate copolymer. The results showed that heat resistance of acrylate polymer was greatly improved with the successful introduction of silicone link.
