摘要
近年来,在无机粉末存在下进行无乳化剂或无皂乳液聚合作为制备复合材料的一种方法正日益引起兴趣。Hasegawa等对不同的无机粉末存在下甲基丙烯酸甲酯(MMA)的无皂乳液聚合进行了研究。Arai、Konno则对无机粉末存在下MMA体系的无皂乳液聚合的动力学及聚合物粒子的成核过程进行探讨。目前的工作主要集中在均聚方面,而对于无机粉末存在下疏水性单体的无皂乳液共聚合,至今报道甚少。
To investigate emulsifier-free copolymerization in the presence of a solid phase, copoly-merization experiments were carried out for the Styrene-Butyl Acrylate-K2S2O8-Water system by using barium sulfate powder, which is assumed to be chemically inert. Reactions were varied with respect to ranging barium sulfate powder quantity, initiator concentration and temperature. These factors were inquired into effect on reaction rate and conversion , polymer particle number and diameter,and latex stabililty.
