【Abstract】 Linear homopolymers and hydrogels of diallyldimethylammonium chloride (DADMAC) were synthesized by gamma irradiation. The relationships between conversion, molecular weight and dose of the polymerization were studied. The results show that the relationship between the gel fraction and dose is in accord with Charlesby Pinner Equation. From the equation, ( D g), G(x ), p, q and M c were calculated. According to the linear relationship between the conductivity and the concentration of DADMAC monomer or homopolymer aqueous solution, the electrical conductivity was first used to detect the conversion of the radiation polymerization.更多还原
