PSt／P（BA－BOA）复合乳液性能的研究

STUDY ON THE PROPERTIES OF POLYSTYRENE/P(BUTYLACRYLATE BUTOXY METHYLACRYLAMIDE) EMULSION

以丁氧基甲基丙烯酰胺（ＢＯＡ）为活性单体，采用种子乳液聚合方法制备了ＰＳｔ／Ｐ（ＢＡ－ＢＯＡ）〔聚苯乙烯／聚（丙烯酸丁酯－丁氧基甲基丙烯酰胺）〕核壳型复合乳液．用透射电子显微镜观察了乳液粒子的微观状态，采用粒度分析仪测定了乳液粒子的粒径及其分布，对乳液的流变性能进行了测试．考察了聚合方式。

PSt/P(BA BOA) core/shell composite emulsion was prepared by seed emulsion polymerization. The morphology, size and distribution of particles were characterized by TEM and PCS; the rheological properties of copolymer emulsion were studied, moreover, the effects of polymerization methods and emulsifier content on the size, distribution of particles and the rheological property were investigated.
