伴有水解缩合反应的自由基种子乳液聚合反应是制备有机-无机杂化乳胶粒的一种新方法,水解缩合反应和自由基聚合这两种反应在乳液体系中的动力学耦合过程决定了聚合产物的微结构和应用性质。通过单体的分配系数建立了单体在乳液体系中各相的分配模型,进而建立了考虑单体分配的自由基种子乳液共聚合的动力学模型。针对功能基团在乳液各相中水解缩合反应的特点,结合自由基种子乳液共聚合的动力学模型,建立了伴有水解缩合反应的自由基种子乳液聚合动力学模型。该模型反映了反应过程中的物质传递规律、非均相反应特点、自由基共聚合和水解缩合反应间的耦合关系。
The free radical seed emulsion polymerization with hydrolysis and condensation reaction is a new method for preparing organic-inorganic hybrid latex particles. The kinetic coupling process of hydrolysis and free radical polymerization in the emulsion system determines the polymerization Microstructure and Applied Properties of Products. The distribution model of the monomer in the emulsion system was established by the partition coefficient of the monomer, and the kinetic model of the free radical seed emulsion copolymerization was established. According to the characteristics of hydrolytic condensation of functional groups in each phase of emulsion, kinetic model of free radical seed emulsion with hydrolysis and condensation reaction was established based on the kinetic model of free radical seed emulsion copolymerization. The model reflects the law of material transfer during the reaction, the heterogeneous reaction characteristics, the coupling between free radical copolymerization and hydrolysis condensation reaction.
