选用苯乙烯（Ｓｔ）、丙烯酸丁酯（ＢＡ）和少量的Ｎ，Ｎ—二甲基，Ｎ—丁基，Ｎ—（３—甲基丙烯酰胺基）丙基溴化铵（ＤＢＭＰＡ），以阳离子自由基型引发剂进行无皂乳液聚合，合成了稳定的无皂阳离子共聚物乳液，用粒度分布仪表征了胶平均直径、数目，用离子交换—电导滴定分析胶粒表面性质；通过表面张力、ＤＳＣ等分析了胶乳的稳定性和胶膜的结构性能。
Styrene (St), butyl acrylate (BA) and a small amount of N, N-dimethyl, N-butyl and N- (3- methacrylamido) propyl ammonium bromide (DBMPA) Cationic free radical initiator was used for soap-free emulsion polymerization to synthesize a stable soap-free cationic copolymer emulsion. The average diameter and number of the gel were characterized by particle size distribution analyzer. The surface properties were analyzed by ion exchange-conductometric titration. , DSC and other analysis of the stability of the latex and the structural properties of the film.
