Morphology of micron-sized, monodisperse, nonspherical polystyrene/poly(n-butyl methacrylate) composite particles produced by seeded dispersion polymerization

Abstract

Nonspherical polystyrene (PS)/poly(n-butyl methacrylate) (PBMA) composite particles with uneven surfaces were produced by seeded dispersion polymerization of BMA with 1.65-μm, monodisperse, spherical PS seed particles. The composite particles consisted of a PS core and an incomplete PBMA shell. The formation mechanism of such nonspherical particles was discussed. © 2002 John Wiley & Sons, Inc. J Appl Polym Sci.
