Porosity variation and swelling of styrene-divinylbenzene copolymers
Polymer Bulletin, 1980The porosity measured for two series of diluent-modified styrene (S) — divinylbenzene (DVB) copolymers (10 and 20 wt.-% of DVB) was found to depend on sample pre-treatment. A correlation between the volume fraction of the polymer in the swollen gel and the volume fraction of octane used as diluent has been established assuming the isotropic swelling of

Adsorption of mercury(II) on macroreticular styrene—divinylbenzene copolymer beads
Talanta, 1979The adsorption characteristics of mercury(II) on several kinds of styrene-divinylbenzene copolymer beads having different surface properties were studied. It was found that the polymer beads selectively adsorbed mercury(II) from solutions over a wide range of pH with high efficiency.

Fluorinated styrene divinylbenzene copolymer as catalyst support
Applied Catalysis, 1991Abstract Styrene divinylbenzene copolymer (SDB) is an inert high surface area material suitable for supporting noble metal catalysts. Because SDB is hydrophobic, the resulting catalysts are free from capillary condensation and remain active in the presence of water. Although SDB supported catalysts are stable at moderate temperatures, it is desirable

Effects of post-crosslinking of macroreticular styrene–divinylbenzene copolymers on their morphology
Polymer, 2006Abstract We performed a detailed comparison of properties of two different styrenic polymers containing divinylbenzene as the crosslinker before and after the introduction of the additional crosslinks by Friedel–Craft's reaction of the residual double bonds.

Surface sulphonated highly crosslinked styrene‐divinylbenzene copolymers
Die Angewandte Makromolekulare Chemie, 1988AbstractA series of surface sulphonated macroporous styrene‐divinylbenzene (S‐DVB) copolymers containing various amounts of —SO3H groups was obtained. Porous structure, surface hydrophilicity and polarity, and sorption properties of these copolymers as well as those of starting S‐DVB resin towards some substances which are present in blood were ...

AN OVERVIEW OF HYDROPHOBIC CATALYST OVER STYRENE-DIVINYLBENZENE COPOLYMER
Chemical Engineering Communications, 2012Recently developed catalytic processes with hydrophobic catalysts supported over styrene-divinylbenzene copolymer (SDB) were reviewed. Applications of such catalytic processes in commercial chemicals production and environmental management were examined in great detail.

Styrene‐divinylbenzene copolymers for high‐performance proppant applications
Polymer Engineering & ScienceAbstract This study focuses on developing and characterizing polymer‐based materials for high‐performance applications as proppants in oil and gas wells. We use styrene‐divinylbenzene (Sty‐DVB) copolymers as the base, incorporating additives such as polybutadiene (PB) and polyphenylene oxide (PPO).

Catalytic properties of cobalt(II) porphyrins supported on styrene-divinylbenzene copolymer
Journal of Applied Polymer Science, 1996Polymeric pyridinium chloride was synthesized by treating pyridine with 2% divinylbenzene (DVB)-crosslinked chloromethyl polystyrene. Sodium 5,10,15,20-tetrakis(4-sulfophenyl)porphyrin was synthesized and appended on the above polymer through an ionic linkage.
