The monodisperse micron-sized polystyrene particles crosslinked with polyet
her diol diacrylates were produced by a simple dispersion polymerization in
an ethanol solution. Unlike conventional divinylmonomers, the polyether di
ol diacrylates used as a crosslinker showed an excellent effect on maintain
ing the particle monodispersity even in a moderate crosslinker concentratio
n. It is believed that the monomer-diffusible surface of primary particles
played a decisive role in achieving the monodispersity of final particles b
y suppressing the second nucleation. The importance of monomer-diffusivity
was tried to understand systematically in producing the crosslinked micron-
sized polymer particles by the dispersion polymerization. (C) 2001 Elsevier
