Pore memory of macroporous styrene-divinylbenzene copolymers

Journal of Applied Polymer Science, 1999
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 toluene- cyclohexanol mixtures as a diluent.

Styrene-divinylbenzene copolymer grafted with phosphonic acid dialkyl esters

Journal of the Serbian Chemical Society, 2004
The functionalization of a crosslinked chloromethylated polystyrene 8% divinylbenzene copolymer with phosphonic ester groups is detailed. The reacton conditions were studied in order to determine the optimal conditions for obtaining only diesters. Astatistical method for the calculation of the fraction of repetive units for the inited and final resin ...
