摘要
以较大水溶性单体甲基丙烯酸甲酯乳液聚合体系为研究对象,利用膨胀计研究了在一定温度一定搅拌速度下乳化剂及引发剂浓度对聚合反应速率、乳胶粒直径及数目以及聚合物分子量的影响,并将试验数据与低水溶性单体乳液聚合数学模型预计的结果进行了拟合,得到了对于乳液聚合过程数学模型化很有价值的结论。
In the present work the effects of the concentration of the emulsifier and initiator on the polymerization rate, the size and number of latex particles and the molecular weight of polymer under a constant temperature and a fixed rotating speed conditions are studied for a more water-soluble monomer, methylmethacrylate, by use of a diatometer. Besides, the experimental data are fitted to the predicted results by the mathematical model of emulsion polymerization for poor water-soluble monomers. Valuable conclusions are reached for modelling emulsion polymerization processes.
