摘　　要：采用水相核-壳乳液聚合法,分别以甲基丙烯酸甲酯和丙烯酸丁酯为主要硬单体和软单体,以丙烯酸为功能单体,制备核壳型聚丙烯酸酯硬挺剂,通过对单体、乳化剂、引发剂、电解质等的选择或用量优化,以及聚合反应温度的控制,优化了聚丙烯酸酯硬挺整理剂的制备条件:甲基丙烯酸甲酯(MMA)∶丙烯酸丁酯(BA)∶苯乙烯(ST)∶丙烯酸(AA)=48∶27∶12∶3(质量比),乳化剂4%(对单体重,下同)、阴非离子乳化剂质量比3∶1,引发剂过硫酸铵0.4%,电解质碳酸氢钠0.4%,聚合反应温度85℃;在该条件下制备得到的硬挺剂乳液性能稳定。将其用于涤纶机织物硬挺整理,可使织物抗弯长度从1.8 cm提高至4.8 cm,且整理效果具有较好的耐洗性,织物白度和强力几乎不受影响。Potyacrylate stiffening agent with core-shell structure is prepared by core-shell emulsion po- lymerization method with methyl methacrylate as a hard monomer, butyl acrylate as a soft monomer, and acrylic acid as a functional monomer. The optimal polymerization process is obtained as follows： mass ratio of M MA：BA：ST：AA is 48：27：12：3, 4% of emulsifier and the mass ratio of anionic to nonionic is 3： 1, 0.4% of initiator, 0.4% of sodium bicarbonate, the polymerization temperature 85 ℃. The results show that the stiffening agent has good stability.The finished polyester fabric features improved bend- ing length from 1.8 cm to 4.8 cm, good washability, unchanged whiteness and strength.
