Application of Fluorescence Probe Technique in the Optimization of Polymerization Reaction of Acrylic Emulsion
Pages: 4-8

Journal: Paint & Coatings Industry

Abstract: 采用芘荧光探针,通过对比分析芘第一振动峰(I1,373 nm处)和第三振动峰(I3,384 nm处)的荧光强度之比(I1/I3)在不同乳化剂配比[m(AS):m(OP)]、乳化剂用量、引发剂用量及pH条件下的变化规律,利用其斜率的绝对值|K|表征了聚合反应速率,并结合单体转化率,对丙烯酸酯乳液聚合工艺进行了优化.研究结果显示:当乳化剂配比、乳化剂用量、引发剂用量及pH分别为2∶1(质量比)、5%(...
