摘    要:采用半连续种子乳液聚合法,以甲基丙烯酸(MAA)为功能性单体,考查MAA的加入量、加入方式和中和度对乳液耐水性能的影响,合成了醋酸乙烯/叔碳酸乙烯酯/甲基丙烯酸(VAc/Veova10/MAA)三元共聚乳液。改性共聚乳液干强度为951MPa,湿强度为377MPa,吸水性为47.0%。电导滴定法分析MAA共聚后,部分竣基基团分布于乳胶粒子表面。提高乳液的耐水性能;扫描电镜(SEM)观察乳胶颗粒分散均匀。合成的共聚乳液可用作木材胶粘剂。

关 键 词:聚醋酸乙烯  乳液  耐水性  甲基丙烯酸

Abstract:Water-resistant copolymer latexes of vinyl acetate(VAc)/vinyl ester of versatic acid(Veova)/ methacrylic acid (MAA)were prepared by the semi-continuous seeding emulsion polymerization. The water resistance of these latexes was greatly dependent on the MAA content, the introduction method of MAA and the neutralization degree of MAA. The results showed that water-resistant VAc/ Veova /MAA latex had 9.51 MPa of dry compression shear strength , 3.77 MPa of wet compression shear strength and 47.0% of water absor...
Keywords:plolyvinyl acetate  latex or emulsion  water resistance  methacrylic acid
