Abstract
The present paper covers the synthesis of styrene—2,2-bismethacryloyloxyphenyl propane (bisvinyl-A) copolymers, which have been prepared by suspension copolymerization in the presence of toluene (Tol) and isoamyl alcohol (Iso) as diluents. 2,2-Bismethacryloyloxyphenyl propane (bisvinyl-A) as a novel crosslinking agent is first used in the synthesis of the styrene-type copolymer. A series of the macroporous and high crosslinking copolymers has been synthesized under different reaction conditions. Characterization of the copolymer beads was carried out through the determination of the apparent density, specific area, pore volume and pore size. The effects of the toluene/isoamyl alcohol ratio, the degree of dilution, and the amount of bisvinyl-A on the surface morphology of the copolymer beads were examined using scanning electron microscopy. It was found that the porosity of the copolymer beads obtained was related to the amount of crosslinking agent, the kind and amount of diluents and the degree of dilution.
