摘要
采用半加续种子乳液聚合技术合成了含甲基丙烯酸缩水甘油酯（ＧＭＡ）、甲基丙烯酸羟乙酯（ＨＥＭＡ）和甲基丙烯酸二甲氨基乙酯（ＤＭＡＥＭＡ）的室温自交联乳液（ＧＨＤ），研究了聚合工艺和配方对ＭＭＡ－ＢＡ－ＨＥＭＡ－ＤＭＡＥＭＡ体系的聚合过程稳定性的影响，除了聚合过程中形成的水溶性聚合物的架桥凝聚作用之外，反应性官能团间的交联凝聚作用对ＧＨＤ乳液聚合稳定性有重要影响。
The GHD latex containing glycidyl methacrylate (GMA), hydroxyl methacrylate (HEMA) and dimethylaminoethyl methacrylate (DMAEMA), which is crosslinkable at ambient temperature, is synthesized in seeded emulsion polymerization. The effects of the polymerization technology and the recipes on the process stability of the emulsion copolymerization(PSEC) of the MMA_BA_HEMA_DMAEMA in the presence of the seed latex are investigated. The effect of the cross linking coagulation of the reactive groups is found to have influence on the PSEC, besides the bridging effect of the water solvable polymer formed during the polymerization. Yet, the content of the HEMA and DMAEMA has little effect on the PSEC.
