【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.更多还原
