摘要
聚二烯丙基二甲基氯化铵 (简写P -DADMAC)是胶体滴定技术中应用的标准阳离子聚合电解质。本文研究了P -DADMAC的合成方法和引发剂用量、反应温度、反应时间、通氮气等影响因素 ,P -DADMAC相对分子质量与电荷密度之间的关系 ,pH值对P -DADMAC电荷密度的影响 ,并利用制得的标准阳离子聚合电解质P
P-DADMAC is a standard cationic polyelectrolyte in colloid titration. This paper focuses on the method of synthesis of P-DADMAC, such factors as amount of initiation, temperature, reaction time and nitrogen feed, the relationship between molecular weight and charge density, the effect of pH value on charge density. Charge density of APAM and anionic dispersed rosin size at different pH value are measured with colloid titration using P-DADMAC and standard anionic polyelectrolyte——PVSK.
