摘要
研究了阳离子型共聚单体甲基丙烯酰氧乙基三甲基氯化铵（DMC）的用量对甲基丙烯酸甲酯（MMA）／丙烯酸丁酯（BA）／DMC无皂乳液聚合速率、聚合物在THF中的溶解性、乳液稳定性及pH值的影响。实验结果证明，此体系中所生成的乳胶粒子均匀，表面清洁，并且DMC含量在1．5wt％～3．5wt％时（建立在BA和MMA总质量基础上），乳液具有较高的稳定性。
The effect of cationic comonomer methacryloyloxy ethyl trimethylammonium chloride （DMC） on the rate of polymerization, the dissolvability of polymer in THF, the stability and pH value of methyl methacrylate （MMA）/butyl acrylate（BA）/DMC soap-free emulsion were studied systematically. The results show that the particles in the latex are uniform and have clean surfaces. When the DMC content is between 1.5 wt % - 3.5 wt % （based on total mass of BA and MMA）, the latex has high stability.
