摘要：

通过可逆加成断裂链转移聚合方法制备了聚甲基丙烯酸二甲氨基乙酯（PDMAEMA）均聚物,利用溴化苄对PDMAEMA进行季铵化得到一系列不同季铵化程度的PDMAEMA季铵盐。通过核磁共振波谱、凝胶渗透色谱、表面张力测试、动态光散射和Zeta电位对产物进行表征和性质分析。实验结果表明成功制备了PDMAEMA和聚季铵盐,芳基季铵化的PDMAEMA具有优良的表面活性,在25 g/L质量浓度下季铵化程度对其表面张力值影响不大。季铵化后的聚合物粒子流体力学直径变大。随季铵化程度增加,PDMAEMA季铵盐的温敏性逐渐消失。

Abstract:

Polydimethylaminoethyl methacrylate （PDMAEMA） homopolymer was prepared by reversible addition fragmentation chain transfer polymerization method, and a series of PDMAEMA quaternary ammonium salts with different degrees of quaternization were synthesized by quaternization with benzyl bromide. The products were characterized by NMR spectroscopy, gel permeation chromatography, surface tension test, dynamic light scattering and Zeta potential analysis were carried out for studying their properties. The results show that PDMAEMA and polyquaternary ammonium salts have been successfully prepared. The aryl quaternized PDMAEMA has excellent surface activity, and the degree of quaternization has little effect on its minimum surface tension. The particle size of the quaternized particles above 40% is obviously increased. As the degree of quaternization increases, the temperature responsibility of PDMAEMA quaternary ammonium salt gradually disappears.

Key words: poly（dimethylaminoethyl methacrylate）, quaternary ammonium, temperature-sensitivity, surface activity
