| 摘 要： | 在不加入任何传统乳化剂的情况下,以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为表面活性功能单体(surfmer),作用于乙酸乙烯酯(VAc)与丙烯酸丁酯(BA)的共聚乳化体系中,成功制备了一种新型的P(VAc/BA/AMPS)三元无皂乳液,该乳化体系在聚合以及贮存过程中都表现出良好的稳定性。考查了单体配比、AMPS用量、引发剂用量、反应温度和反应时间等条件对乳液性能的影响。确定的最佳单体配比为mVAc:mBA=8:2,AMPS用量为单体质量的1.0%,引发剂过硫酸钾(KPS)用量为单体质量的0.6%,反应温度为80℃。所制得的乳液粒径约为144nm,且单分散性好,固含量在42%以上。

| Abstract: | Without adding any conventional emulsifier,using 2-acrylamido-2-methylpropane sulfonic acid(AMPS) as the surfactant monomer(surfmer),a new type of P(VAc/BA/AMPS) terpolymer soap-free emulsion is successfully prepared.The emulsion system had desirable stability cluring the polymerization process and its storage of six months.This article examined the influence of ratio of monomers,AMPS dosage,initiator dosage and reaction temperature on the properties of the terpolymer emulsion.The obtained optimum condition... |
