摘　　要：采用预乳化半连续种子乳液聚合法，以失水山梨醇单油酸酯聚氧乙烯醚磺基琥珀酸二钠、脂肪醇聚氧乙烯醚磺基琥珀酸酯二钠、烷基酚聚氧乙烯醚（ OP-10）为复配乳化剂，以甲基丙烯酸甲酯、丙烯酸丁酯和丙烯酸为共聚单体，制备了颜料用丙烯酸酯乳液。采用黏度计、光泽度仪、离心机、红外光谱、透射电镜、粒径测试等对聚合物结构和性能等进行了分析与表征。结果表明，乳液固含量为46%、光泽度为80.2，乳液各项稳定性较好；乳液聚合程度较高，乳液平均粒径DH 为128 nm，分子量分布指数（ PDI）仅为0.083，粒径分布较窄；TEM图谱显示聚合物具有规整的球形结构，且粒径分布相对均一，粒径绝大多数在60~95 nm，且与PCS图谱结果保持一致。The acrylic resin of high brightness and high gloss were PrePared from methyl methacrylate （ MMA）,butyl acrylate（ BA）and acrylic acid（ AA）by the method of Pre-emulsification and semi-con-tinuous seed emulsion Polymerization,according to disodium Polyoxyethylene sorbitan monooleate sulfos-uccinate,disodium alkyl Polyoxyethylene sulfosuccinate and Phenol Polyoxyethylene ether（ OP-10 ）were used as the comPlex emulsifiers. The structure and ProPerties of Polymers were characterized by viscosime-ter,gloss meter,centrifuge,FTIR,TEM and Particle testing. The results showed that the emulsion with high solid content（ 46%） and good stability was synthesized;the exPerimental Products achieved the market Performance of similar Products which brightness is 80 . 2 . The average Particle size and distribu-tion were measured by PCS and the hydrodynamic diameters were 128 nm,and the PolydisPersity index （ PDI）was 0. 083. The morPhology of latex Particles were examined by TEM,and the images showed that the Particles were sPhere-shaPed with the diameter at 60~95 nm,whose size was in good agreement with the measurement results from PCS.
