摘要：

Styrene-divinylbenzene copolymers have been synthesized by suspension polymerization in the presence of toluene and heptane as diluents for the monomers. The effects of toluene/heptane ratio, degree of dilution of the monomers and divinylbenzene(DVB) content on the surface formation of the copolymer beads were examined by scanning electron microscopy. The sizes of the aggregates and macropores increased with increase of the nonsolvating diluent content and by the degree or dilution of the monomers. The effect of the DVB content was generally the same as that of the diluent for the monomers.
