Narrow-disperse and monodisperse crosslinked core–shell polymer particles containing different functional groups, such as esters, hydroxyls, chloromethyls, carboxylic acids, amides, cyanos, and glycidyls, in the shell layers in the micrometer size range were prepared by a two-stage precipitation polymerization in the absence of any stabilizer. Commercial divinylbenzene (DVB), containing 80% DVB, was precipitation polymerized in acetonitrile without any stabilizer as the first-stage polymerization and was used as the core. Several functional monomers, including methyl methacrylate, ethyl methacrylate, butyl methacrylate, 2-hydroxyethyl methacrylate, glycidyl methacrylate, methyl acrylate, ethyl acrylate, butyl acrylate, t-butyl acrylate, i-octyl acrylate, acrylic acid, acrylamide, acrylonitrile, styrene, and p-chloromethyl styrene, were incorporated into the shells during the second-stage polymerization. The resulting core–shell polymer particles were characterized with scanning electron microscopy and Fourier transform infraredspectroscopy.
