Synthesis and characterization of composites with sulfonated styrene-divinylbenzene copolymer
Macromolecular Materials and Engineering, 2000 In this work light sulfonation was applied to a styrene copolymer crosslinked with divinylbenzene (PS-co-DVB). Subsequently the product was incorporated at different concentrations into poly(vinylidene fluoride) (PVDF) and ethylene-propylene-diene (EPDM). Also, antimonic acid (HSb) was added.

Telomerization of Isoprene with Short Alcohols Using Novel Solid Molecular Phosphine Polymers
ChemCatChem, Volume 18, Issue 8, 28 April 2026.Solid molecular catalysts based on triphenylphosphine and tris(o‐methoxyphenyl)phosphine were designed and loaded with palladium via pre‐loading or in‐situ‐loading for use in telomerization with short alcohols. The pre‐loaded catalyst proved to be significantly more active.

Porous structure of highly crosslinked styrene‐divinylbenzene copolymers
Die Angewandte Makromolekulare Chemie, 1984 AbstractPorous structure of two series of styrene (S)‐divinylbenzene (DVB) copolymers has been studied. The copolymers were prepared by suspension copolymerization of the monomers (50 wt.‐% of DVB) in the presence of heptane‐toluene mixtures as inert diluents.

Journal of Polymer Science, Volume 64, Issue 7, Page 1553-1567, 1 April 2026.An efficient strategy for preparing monodisperse crosslinked polymer microspheres with phenylsulfonate via precipitation polymerization has been successfully established. Monodisperse microspheres are successfully obtained using a designed crosslinker even when the total crosslinker content was below 20 mol%. All the polymer microspheres possess a well‐

ChemSusChem, Volume 19, Issue 5, 13 March 2026.This study presents a practical aerobic photochemical strategy for the upcycling of polystyrene waste, combining bromine radical mediation with InBr3 catalysis. The approach efficiently depolymerizes diverse PS materials under mild conditions, yielding benzoic acid and enabling downstream production of value‐added compounds. The photochemical upcycling
