STUDIES ON EMULSIFIER-FREE EMULSION COPOLYMERIZATION OF METHYL METHACRYLATE-BUTYL ACRYLATE-SODIUM UNDECYLENIC ACID I. KINETICS AND MECHANISM
甲基丙烯酸甲酯-丙烯酸正丁酯-ω-十一烯酸钠无皂乳液共聚合研究——Ⅱ.动力学及反应机理

Emulisifier-free copolymerization of methyl methacrylate (MMA) and butyl acrylate (BA) in the presence of surface active comonomer, Sodium undecylenic acid (at concentration below its CMC) are carried out. The influence of polymerization conditions such as SUA content, KPS content and ionic-strength on kinetics are examined. The particle diameter, number , morphology, growing process,as well as polymerization mechanism are studied by means of Particle Size Analysizer,TEM, GPC,IR Spectra and Ionic-Exchange-Conductimetric titra-tion. The results indicated that particles are generated through a combination of homogeneous nucleation and micellar nucleation mechanism.
