| 摘 要： | 颜料在工业生产和人们的日常生活中起着重要的作用.由于颜料颗粒具有较大的比表面积和较高的比表面能,是热力学不稳定体系,当分散在介质中时容易发生团聚,影响其特性的发挥1],因此需加入分散剂使其在分散介质中稳定分散.

| Abstract: | The reduced Schiff base reacted with ethylidene bromide,and then reacted with Polyvinyl acetate(PVAc) through the phase transfer catalysis of tetrabutyl ammonium bromide,in order to prepare the comb polymer dispersant containing solvation chains of PVAc.Furthermore,the effect of alcoholysis degree of PVAc chains and addition amounts of the comb polymer disperant on the dispersion of titanium dioxide in water were studied. |
