✦ Synopsis

The polymerization of isodecyl acrylate (ISODAC) in vesicles made from an anionic surfactant-sodium di-2-ethylhexyl phosphate (SEHP)-and from water is studied by 'H-NMR, transmission electron microscopy, and quasielastic light scattering. High polymerization rates and high conversion rates are achieved with both water-soluble initiator, K2S20s (potassium persulfate), and oil-soluble initiator, AIBN (azoisobisbutyronitrile). IS- ODAC is probably located inside the vesicle bilayer(s) because of its high hydrophobicity. Particles stable at room temperature with a mean diameter of about 50 nm are obtained. Kinetic orders of ISODAC polymerization are determined and the characterization of the resulting particles during and after polymerization are studied. 0
