Porous copolymers of N-vinylcarbazole (NVC) and divinylbenzene (DVB) of different composition (crosslinking degree) have been studied. The copolymers were obtained by suspension polymerization carried out in the presence of diluents, mixtures of 'good' (isopentanol and toluene) and 'bad' solvents (dodecane and toluene). The supermolecular structure of the copolymers was found to depend not only on the crosslinking degree, but on the thermodynamic quality of diluents. In the presence of good solvents, copolymers of the porous-gel type were formed at relatively small crosslinking degree (< 200% DVB). Sorption properties of porous NVC-DVB copolymers with respect to p-nitrophenol were found to be similar to those of acrylonitrile-DVB copolymers.
