摘　　要：以甲基丙烯酸甲酯(MMA)为单体,水为分散介质、聚乙烯醇(PVA)为分散剂、采用不同引发剂,利用悬浮乳液聚合法制备单分散聚甲基丙烯酸(PMMA)微球。系统研究了搅拌速度、不同W/O比、乳化剂种类对聚合反应及产物的影响。结果表明,PMMA微球粒径在75℃、230r/min条件下,采用复合乳化剂(DOWFOXA1、SE-10N、EC403)、油性引发剂引发聚合,产物粒径大小及分布最好。The methods Based on MMA as monomers, water as disperse medium, PVA as dispersant, adopt the different initiator, prepared by suspended emulsion polymerization of monodisperse poly （methyl acrylic（PM- MA） microspheres. This paper studied the mixing speed, W/O ratio, emulsifier types influence on polymerization reaction and product. The results showed that PMMA microspheres particle size under the condition of 75 ℃, 230 r/min, with composite emulsifier（DOWFOXA1, SE-10n, EC403）, oily initiator, polymerization, particle size and distribution of the best.
