摘要： 以在低温下(<100℃)实现含羧基/环氧树脂的丙烯酸酯共聚物乳液的交联固化为目的,进行了分子设计;估算了共聚物的组成,用碱滴定法测定了乳胶粒表面的羧基数,并比较了不同单体配比所得乳液的成膜性能.

关键词: 丙烯酸酯共聚物, 乳胶粒表面羧基测定, 共聚物组成

Abstract: The purpose of the article is try to carry out the crosslinking reaction of acrylate copolymer latex containing carboxyls/epoxy resin.According to the molecular design,the composition of the copolymer was first calculated and the synthetic method of latex was studied.With the help of 1H NMR and acid-base titration,the number of carboxyl group in the copolymer and on the surface of latex particles was determined,the film forming characteristics of latex with different monomer ratio was also compared.

Key words: Acrylate copolymer, Determination of the number of carboxyls on surface of latex particles, Composition of copolymer
