| Abstract: | Poly(vinyl chloride) was modified by triethylene-tetramine(TTA) with different ratios of(reactants) and reaction time to obtain a series of aminated products,then these products were quaternized(using) dimethyl sulfate.The structure of the obtained products were characterized by element analysis and FT-IR.The physico-electrochemical characters of cationic polymer flocculant were examined by charging density,intrinsic viscosity,and Zeta potential.The results indicate that through controlling the synthesis co... |
