Abstract Commercial ion-exchange resins (Amberlyst 35 and Amberlyst 36) and a resin synthetized in the laboratory, sulfonated poly(divinylbenzene) were evaluated as catalysts in the esterification of fatty acids (palmitic and oleic) with alcohols (methanol, ethanol and butanol).

Polyvinylpyridine-divinylbenzene and asbestos composites
Polymer, 1984Abstract The in situ copolymerization of vinylpyridine and divinylbenzene in crysotile asbestos cardboards yields composites of higher mechanical strength and chemical stability than plain carboard. The composites have been tested as gasket rings and separators of advanced alkaline water electrolysers.

AbstractPolymeric supports based on divinylbenzene (DVB) were prepared by aqueous suspension polymerization in presence or absence of styrene (S), using toluene and n‐heptane as diluents of the monomers. Poly(S–DVB) and poly(DVB) were sulfonated with sulfuric acid in presence of 1,2‐dichloroethane.

A kinetic study of the polymerization of pure meta‐divinylbenzene and pure para‐divinylbenzene
Journal of Polymer Science Part A: Polymer Chemistry, 1999The kinetics of the polymerization of pure meta-divinylbenzene (DVB) and pure para-divinylbenzene at 70°C have been studied in the presence of toluene and 2-ethylhexanoic acid. The apparent rate constant ratios (kp/kt)1/2 for these systems have been calculated.
