摘要
以聚乙烯吡咯烷酮(PVP)为分散剂,偶氮二异丁腈(AIBN)为引发剂,乙醇/水混合溶剂为分散介质,用分散聚合方法制备出微米级甲基丙烯酸甲酯-苯乙烯共聚物微球。研究了分散介质组成、单体质量比、分散剂用量、反应温度等反应条件对聚合产物粒径及粒径分布的影响。并用红外光谱对产物结构进行了表征。
Micron -size methyl methacrylate -styrene copolymer microspheres were prepared by dispersion copolymerization in the presence of ethanol/water mixture, using polyvinylpyrrolidone （PVP） as dispersant and stabilizer and azobisiobutyronitrile（AIBN） as initiator. The effects of ethanol/water ratio, monomer mass ratio, PVP concentrations and reaction temperature on the particle size and size distribution were studied. The structure of product was characterized by FT - IR.
