建筑密封膏用醋丙乳液胶粒的羧基化处理

Studies on morphology of carboxylated EVA/BA composite latex

摘要: 合成了一系列醋酸乙烯-丙烯酸丁酯-丙烯酸等单体共聚乳液样品,研究了聚合条件对乳液胶粒表面羧基分布的影响,并对其碱增稠性进行了讨论.结果表明,因聚合物组成、条件不同,胶粒表面羧基分布有明显的不同,而且具有不同的碱增稠特性.

Abstract: A series of carboxylated EVA/BA more monomer copolymer latexes was prepared by using different copolymerization . The distribution of carboxylic group in latexes and alkalic -thicken nature were investigated. The effect of copolymerization methods on the property of the composition were discussed.
