| 摘 要： | 讨论了温度对十一烯酸钠存在下的苯乙烯、丙烯酸丁酯无皂乳液聚合体系pH值的影响,描述了聚合反应动力学曲线,求出不同温度下的聚合反应速率常数.利用TEM对几种乳化剂体系的乳液聚合进行比较后发现,在无皂乳液聚合体系中,乳胶粒的均匀性和粘连、形变等都得到了控制.由于体系中不存在游离乳化剂,乳液的稳定性得到提高.

| Abstract: | The influence of temperature on pH of system of emulsifier-free emulsion polymerization of styrene-butyl acrylate in the presence of sodium undecylenate is discussed.The curve of polymerization kinetics is described.The reaction rate constant(kP)at different temperatures is calculated.Using TEM to compare emulsion polymerization of several emulsifier system,we found that the homogeneity and adhesion and deformation of the particles of emulsion could be controlled.Because there are no free emulsifier,the stability of emulsion is raised. |
