摘要 在MMA和BA的乳液聚合中引入反应性乳化剂DNS—86,从耐水性、附着力、乳胶粒的形态和稳定性等方面考察了乳液的性能。结果表明,通过DNS—86的引入,可获得大小均一、直径0.12μm的乳胶粒子;乳液成膜后浸泡7 d的吸水率和溶出率分别为35.1%和0.4%;附着力1级;无皂乳液的稳定性明显优于传统乳液体系。 A reactive emulsifier (DNS-86) was applied in the emulsion copolymefization of methyl methacrylate (MMA) and butyl acrylate ( BA). The morphology of the latex particles, water resistance, adhesion capacity andd stability of the copolymers were investigated. The copolymer latexes obtained in the presence of DNS-86 consisted of monodispered latex particles with a diameter of ca. 0.12 μm. Experimental results showed that the latex films possessed good adhesion capacity ( grade 1 ) and good stability. Their water - absorbing rate and water - dissolving rate were only 35.1% and 0.40 %, better than those of the common latex films.
