Synthesis of the Crosslinked Functional Polystyrene Microspheres in Micron-Size Monodisperse by Dispersion Polymerization

Hong Zhang

Abstract

Crosslinked functional polystyrene microspheres in micronsize monodisperse was prepared with batck method by using poly(Nviylpyrrolidone)(PVP), azobisisobutyronitrile(AIBN),ethylene glycol dimethacrylate(EGDMA) as stabilzers, initiator and crosslinker, respectively. The effect of initial acrylic acid (AA) concentration, EGDMA concentration, and styrene concentration on the reaction kinetics, particle size and size distribution of polystyrene microspheres were investigated. The content of carboxy on the particle surface was determined.
