摘要
本文研究了含环氧基的丙烯酸酯四元共聚物乳液交联后的溶胀度、自交联反应及动力学.结果表明:交联共聚物的溶胀度Q随甲基丙烯酸环氧丙酯单体含量的增加而降低,共聚物在受热的情况下,环氧基因在羧基的作用下开环而发生交联反应,产生网状结构.
The emulsion of copolymers of acrylates with epoxy group were preparedand characterized by means of swelling capacity. The self crosslinkingreaction of the copolymer was studied by FT-IR. It has been found that theswelling capacity of the crosslinked copolymer films decreased with increaseof the glycidyl methacrylate (GMA) content. The activation energy of thecrosslin-king reaction was obtained. A mechanism of the crosslinking reactionwas proposed.
