    摘要:

    以二甲基二烯丙基氯化铵和丙烯酰胺为原料,采用过硫酸铵—亚硫酸氢钠引发体系,采取一次性加料方法,分步升温工艺,以特征黏度为主要考核指标,对5%阳离子度二甲基二烯丙基氯化铵与丙烯酰胺的共聚物PDA进行了制备工艺优化研究。研究了单体质量分数、聚合反应温度、Na4EDTA用量、引发剂用量和熟化温度等对产物特征黏度的影响。得到的最佳工艺条件是:单体质量分数为16%,聚合反应温度40℃,Na4EDTA用量占单体的质量分数为2.0?0-4,引发剂用量占单体的质量分数为7.4?0-4,熟化温度为60℃,产物PDA特征黏度为19.4dL/g;同时采用傅立叶变换红外光谱和核磁共振技术对PDA进行了结构表征。

    Abstract:

    Using dimethyldiallylammonium chloride and acrylamide as the materials and ammonium persulfate - sodium bisulfate as the initiator, the preparation technologies of copolymer PDA with cationicity of 5% via one-stage addition of the monomers and stepwise increasing temperature were researched by using the intrinsic viscosity as quantitative criterion. The effects of the monomer mass percentage, reaction temperature, Na4EDTA dosage, initiator dosage and maturation temperature on the intrinsic viscosity of product PDA were studied. The results show that intrinsic viscosity of PDA with cationicity of 5% could be up to 19.4dL/g, when the monomer mass percentage was 16%, the reaction temperature was 40℃, the ratio of Na4EDTA mass to monomer mass was 2.0?0-4, the ratio of initiator mass to monomer mass was 7.4?0-4 and the maturation temperature was 60℃. The structure of PDA was characterized by FTIR and NMR.
