Abstract

Polystyrene (PS) seed particles in the size range of one to several microns were prepared by dispersion polymerization and swelling techniques. Seeded polymerization/copolymerization of styrene and poly(ethylene glycol) monomethacrylate (PEGMMA) was then carried out with several-micron-sized PS particles using poly(ethylene glycol)-azo initiator (PEGA). The morphology, size-distribution, and surface properties of the prepared polymer particles were studied by scanning electron microscopy and FT-IR-ATR. The produced polymer particles were fairly monodisperse and spherical. The presence of poly(ethylene glycol) on the surface of polymer particles was observed in the case of composite polymer particles prepared with macromonomer.
