| 摘 要： | 用乳液接枝聚合方法制备环氧树脂／丙烯酸树脂的复合胶乳水分散体系，考察了不同引发剂用量、乳化剂用量、单体浓度对复合胶乳粒径、接枝率、分子量的影响，并对这类复合胶乳体系的接枝机理进行了探讨。实验结果表明，引发剂浓度增大，粒径增大，分子量减小，接枝率增大；乳化剂浓度增大，分子量和接枝率变化不大，粒径则有下降趋势；环氧树脂浓度增大，粒径倾向于增大，分子量和接枝率则显著降低。说明缩聚物／加聚物接枝乳液聚合与一般乳液聚合规律有所不同。

| Abstract: | A waterborne epoxy acrylic graft latex was synthesized. The effect of initiator, emulsifier, epoxy concentration on the particle size, molecular weight and the grafting ratio of the composite latex were investigated. The result indicated that the molecular weight decreases, the grafting ratio and particle size increase with the increase of initiator concentration. The increase of emulsifier concentration just leads to the decrease of particle size. When the epoxy concentration increases, the molecular weight and the graft rate decreases rapidly. It is concluded that the rules of the graft polymerization of addition/condensation composite latex are different from those of common emulsion polymerization. |
