采用种子乳液和半连续乳液聚合法制备了核壳型St／BVA／BA微凝胶，研究了不同乳化剂配比及加入方式、不同引发剂及其加入方式等对乳液聚合转化率及稳定性的影响；对半连续法制备的核壳结构微凝胶进行了结构表征及Ca2+稳定性、稀释稳定性、冻融稳定性等性能测试。
The reactive polymer microgel with core-shell structure was synthesized by seeded emulsion polymerization and by the technique of particle design using styrene. butyl acrylate as monomers and BVA as cross-linking agent. The effect of different emulsifier and adding style on the conversion and stability of St／BVA／BA polymer microgel emulsion and the effect of different initiator and adding style on the stability of St／BVA／BA polymer microgel emulsion were studied. The morphology of St／BVA／BA polymer microgel with core-shell structure was characterized by TEM and DSC and the stability of Ca2+, dilute and freezing were tested.
