摘　　要：介绍了有机硅改性丙烯酸酯聚合物的两种方法:物理改性法(有机硅作为助剂与丙烯酸乳液共混、有机硅聚合物乳液与丙烯酸酯聚合物乳液共混)和化学改性法[缩聚法、加成聚合法(自由基共聚加成、硅氢加成)、核壳乳液聚合、乳液互穿聚合物网络(IPN)法];重点阐述了化学改性方法;展望了有机硅改性丙烯酸酯聚合物的发展趋势.Two modification methods of polyacrylates with silicones are reviewed, i.e., physical and chemical modifications. The physical modification means the uses of silicones as auxiliaries for mixing with acrylic emulsions or as silicone polymers for mixing with acrylic polymer emulsions, and the chemical one includes condensation, adduct polymerization （free radical copolymerization adducting and Si-H adducting）, core-shell emulsion polymerization and emulsion inter-penetration nets （IPN）. The chemical modification is described in details. The development trends of the modification methods are prospected .
