对二甲基二烯丙基氯化铵进行了辐射聚合，得到线型聚合物的交联的水凝胶， 实验测定了线型聚合的转化率与剂量和水凝胶的凝胶的凝胶分数、平衡溶胀与剂量 的关系。结果表明聚二甲基二烯丙基氯化铵水凝胶的凝胶含量与剂量的关系符合 Charlesby-Pinner公式，外推S + S~(1/2) = 2求得凝胶剂量D_g，从而求出G(x) 等值；并首次利用二甲基二烯丙基氯化铵及其聚合物稀水溶液的电导率与浓度的线 性关系，发展了一种对电解质的辐射聚合反应转化率的电导测定法。

Linear homopolymers and hydrogels of diallyldimethylammoniu 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.
