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.
