Abstract: The kinetics of diallyldimethylammonium chloride aqueous solution polymerization whose kinetic mechanism is very complex and unknown,was investigated in a Dewar-reactor by adiabatic calorimetry by applying ammonium peroxydisulfate of 2, 2′-azobis ( 2-aminopropane ) as initiator.The kinetic and thermodynamic parameters were simulated by numerical method.It was found that the calculated values coincided with the experimental data,but there were some differences between the simulated parameters and the published data.It was considered that the differences were caused by the first order assmption of ammonium peroxydisulfate decomposition and the neglect of the side reaction effects in the literature.

摘要： 采用绝热量热法 ,在Dewar聚合釜中研究动力学机理复杂的氯化二烯丙基二甲基铵 (DADMAC)在水溶液中的自由基聚合动力学 ,用数值计算法拟合其动力学和热力学参数 ,计算结果与实验值吻合良好 .与文献值相比 ,两系统的热力学参数基本相同 ,但动力学参数有些出入 .认为这是由于文献中将引发剂 (NH4) 2 S2 O8的热分解简单处理成一级反应而未考虑其副反应的影响造成的 .
