| 摘 要： | 为了解决聚二甲基二烯丙基氯化铵(PDMDAAC)合成时分子量低的问题,采用系统的单因素研究方法,先后对单体质量分数、引发剂用量、聚合反应温度、EDTA-Na4用量、pH值、单体纯度等影响单体聚合的因素进行了较为详细的研究,最终获得了各参数的最佳组合条件,即:反应4 h、聚合温度50℃、单体起始质量分数67%、引发剂质量浓度0.3%、pH5.0、EDTA质量浓度150 mg/L.采用此工艺条件对"-步 两步"法单体进行聚合,得到特性黏度高达2.7 dL/g的PDMDAAC.

| Abstract: | In order to increase the PDMDAAC's molecular weight,this paper introduces the detailed study of the effect of the factors such as DMDAAC's initial concentration,initiator's dosage,EDTA's dosage,polymerizating temperature,pH value,DMDAAC's purity on the polymerization with single-factor method,and highlights the best preparation condition.Adopting this preparation technology,DMDAAC produced with "one two step" method was polymerized, with the result that homopolymerization with intrinsic viscosity of 2.7 dl/g was obtained. |
