Swelling of porous styrene-divinylbenzene copolymers in water

Journal of Applied Polymer Science, 2000
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.

Styrene–divinylbenzene copolymers post-crosslinked with tetrachloromethane

Polymer, 1998
Abstract This paper describes a method of preparation of permanently porous functionalized styrene copolymers by the chemical transformation of gel or macroporous styrene–divinylbenzene copolymers. As a crosslinker, tetrachloromethane was used in the presence of a Friedel–Crafts catalyst (aluminium or ferric chloride).

Chemical modification of styrene-divinylbenzene copolymers by dialkyl phosphites

Polymer, 1986
Abstract Chloromethylated styrene-divinylbenzene copolymers were treated with dialkyl phosphites to obtain cation exchangers with phosphorus-containing acid groups. The gel and macroporous styrene-divinylbenzene (St-DVB) copolymers of Wofatit type were used. The influence of the phosphite (R=CH 3 , C 2 H 5 ) as well as of the copolymer structure (gel,

Temperature effect on tension formation in styrene–divinylbenzene copolymers

Polymer International
AbstractCrosslinked polymers are considered to be promising materials for supporting catalysts that are effectively applied in different reactions. However, the application of polymer‐supported catalysts in high‐temperature processes is limited by their temperature stability.
