摘要
本文研究了在18-冠(醚)-6存在下,苯乙烯和甲基丙烯酸丁酯无乳化剂乳液共聚。发现18-冠(醚)-6能起到相转移催化作用,加速共聚反应。对实验结果提出两相成核的解释。
The emulsifier-free emulsion copolymerization of styrene and Butylme-thylacrylate in the presence of 18-Crown-6 has been studied. We find that 18-Crown-6 can accelerate the copolymerization reaction as a phase transfer eatalyst. From these resulte, a two phase particle nucleation mechanism has been proposed for this copolymerization.
