Structures of copolymers of styrene and divinylbenzene (50% crosslinking degree) prepared in suspension polymerization in the presence of mixtures of nonsol (heptane or decane) and sol (toluene or tetralin) diluents were investigated. The studies showed that the diluents enriched with nonsol solvent
The variation of the pore structure of styrene-divinylbenzene (S-DVB) copolymer beads with the drying conditions was investigated. Macroporous S-DVB copolymer beads with various DVB contents were prepared in the presence of toluenecyclohexanol mixtures as a diluent. It was found that the pores of 10
The swelling capacity of porous styrene-divinylbenzene (DVB) copolymers in water was studied by displacing methanol from the swollen polymer. The copolymers with different amounts of DVB were prepared in the presence of solvents with different solvating powers as inert diluents. Using a solvating so
