摘　　要：本文采用两种方法制备有机硅改性胶乳，通过对改性胶乳膜的表面性能、吸水性和力学性能的测定，探讨了有机硅的影响以及两种改性方法的差异。结果表明：化学共聚改性能明显改善胶乳膜的耐水性和抗污性，而物理共混改性的效果不明显，甚至起不到改性的作用。The silicone modified latexes were prepared by physical blending and copolymerization. The effect Of silicone contents and modification methods on the surface properties,water absorbility and mechanical properties of the latex films were studied in this paper.The results showed for the film modified by copoly-merization,the water absorbility of the film decreased,and the foul resistance of the film was obviously improved. The effect of physical blending was not obvious or even negative.
