Styrenic resins size exclusion chromatography

Styrene-1,3-butadiene copolymers with higher styrene contents (50-70%) are used in latex paints. Styrene and 1,3-butadiene terpolymerized with small amounts of an unsaturated carboxylic acid are used to produce latexes that can be crosslinked through the carboxyl groups. These carboxylated SBR products are used as backing material for carpets. Styrene copolymerized with divinyl benzene yields crosslinked products, which find use in size-exclusion chromatography and as ion-exchange resins (Sec. 9-6). 

FRC of a vinyl monomer with a small amount of divinyl monomer represents one of the simplest methods for synthesizing polymer networks. In these systems, the divinyl monomer acts both as a comonomer and as a crosslinker. One of the most common and studied systems of this type is the copolymerization of styrene (STY) and divinylbenzene (DVB). Poly(STY-cri-DVB) copolymers are widely used as ion-exchange resins and separation media for size-exclusion chromatography, although several other vinyl/divinyl copolymerization systems have also been smdied [18],...
