摘　　要：利用水解抑制法和种子乳液聚合法制备高硅含量的核壳结构有机硅改性丙烯酸酯乳液,讨论了影响聚合过程及乳液稳定性的工艺参数.研究表明,核壳乳液克服了普通硅丙乳液聚合的缺点,尤其是提高了乳液的耐水性.Silicon-acrylate emulsion of high organosiloxane content was synthesized with seed-emulslon polymerization by adding hydrolyzation inhibitor. The influences of several technical parameters on the process of polymerization and the stability of the emulsion were discussed. The experimental results show that the emulsion with the core-shell structure has preferable properties than the generic siliconacrylate emulsion and the water-resistance of coat of emulsion was enhanced.
