摘要
对由无皂乳液聚合法合成的苯乙烯 丙烯酸丁酯 十一烯酸钠高分子电解质 [P (St BA UA Na+) ]胶乳微球在离子介质中的物理化学行为进行了讨论。利用透射电子显微镜 (TEM)对不同介质条件下胶乳微球的形态、粒径及其分布进行了表征 ,认为 Na UA参与了 St、BA的共聚合键连于高分子链上可极大地提高乳化效率和乳液的稳定性 ,其用量对乳胶粒径影响较大 ,介质 p H对胶乳粒径分布有较大影响。
The physicol chemical properties of P (styrene buthyl acrylate sodium undecylenate) electrolyte microsphere synthesised by emulsifier free emulsion polymerization were studied under the condition of ionic environment. The form, particle diameter and particle diameter distribution of polyelectrolyte microsphere under the different pH were characterized by transmission electron micrography(TEM). After having participated copolymerization with St, BA, NaUA bonded emulsion particle, thus, it can heighten emulstification efficiency and stability of emulsion. The particle diameter of latex and the particle diameter distribution can be influenced by the amount of [NaUA] and pH of system respectively.
