Abstract

P(DMDAAC -VTMS)and P(DMDAAC -AM -VTMS), as organic polymer flocculants, are obtained by radical polymerization initiated by composite initiator. The effect of VTMS on the intrinsic viscosity and solubility of the polymers is discussed. The effects of turbidity removal and decolorization of the flocculants are studied. It is found that the introduction of VTMS makes the intrinsic viscosities of P(DMDAAC - VTMS) and P(DMDAAC- AM -VTMS)greater than those of PDMDAAC and P(DMDAAC - AM), respectively. But the solubilities get worse. The effects of turbidity removal and decolorization of P(DMDAAC -VTMS)and P(DMDAAC - AM - VTMS)are better than those of PDMDAAC and P(DMDAAC - AM) respectively.

Key words： organic polymer flocculants; dimethyldiallylammonium chloride (DMDAAC)polymer; vinyl trimethoxysilane(VTMS); radical polymerization; synthesis; water treatment
