摘要

以γ氨丙基甲基二乙氧基硅烷、有机硅封端剂、顺丁烯二酸酐为主要原料，合成了新型的活性有机硅乳化剂，应用于,60,Co γ射线引发的甲基丙烯酸甲酯/丙烯酸丁酯(Methyl methacrylate/Butyl acrylate，MMA/BA )的乳液聚合。用原子力显微镜和红外光谱表征了乳胶粒子形态和结构，研究了乳胶膜的耐水、耐高低温性能和拉伸强度。结果表明，所得丙烯酸酯乳液稳定性好，乳胶粒子呈球形，增加乳化剂用量可显著提高乳胶膜的耐水性和耐高低温性能。

Abstract

A novel kind of polymerizable organosilicone emulsifier (OSE) was prepared with MD,n,M, maleic ahhydride (MA) and γ-aminopropylmerthyldiethoxysilane (SG-Si902). It was applied in the emulsion copolymerization of methyl methacrylate (MMA) and butyl acrylate (BA), initiated by ,60,Co γ-rays. Morphology and composition of the copolymerization latex were investigated by atomic force microscopy and Fourier transform infrared spectroscopy. Properties of the latex films were examined. The results show that the latex emulsified by OSE were stable, and the composite latex has spherical structure. Water-resistant and heat-resistant properties of the latex film were improved remarkably with increased OSE contents.
