Original Contributions


Micron-size monodisperse polymer microspheres having crosslinked structures therein and vinyl groups thereon were prepared by seeded copolymerization of styrene and divinylbenzene with 2,2′-azobisisobutyronitrile as initiator in ethanolwater medium in the presence of 2.1-μm monodisperse polystyrene seed particles produced by dispersion polymerization. The optimum conditions of the seeded copolymerization for producing the microspheres with good monodispersity and colloidal stability were determined.
