Porous maleic anhydride–styrene–divinylbenzene copolymer beads

Journal of Applied Polymer Science, 1987
The formation of the porosity and the pore stability in maleic anhydride–styrene–divinylbenzene (MAn–St–DVB) copolymer beads were investigated using the apparent density measurements of the samples dried from methanol (maximum porosity) and from dioxane (stable porosity).

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

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.

The Sorption of a Polar Pollutant onto Micron-Sized Solids of Different Origins Under Environmentally Relevant Conditions and Assessment of Associated Toxicity Risks

Microplastics
The scientific literature lacks sufficient data on the transport of various toxic pollutants by polymer particles. Investigating how the structure of microplastic particles formed during the degradation of polymeric materials affects pollutant sorption ...

StyA1 and StyA2B from Rhodococcus opacus 1CP: a Multifunctional Styrene Monooxygenase System [PDF]

, 2010
Two-component flavoprotein monooxygenases are emerging biocatalysts that generally consist of a monooxygenase and a reductase component. Here we show that Rhodococcus opacus 1CP encodes a multifunctional enantioselective flavoprotein monooxygenase system

Reversibly collapsible macroporous poly(styrene-divinylbenzene) resins

, 2000
A series of poly(styrene-divinylbenzene) (poly(PS-DVB)) resins have been prepared by suspension polymerisation of styrene-DVB mixtures with DVB contents of 1-12 mol%. In each case 2-ethyl-hexan-1-ol was used as a porogen.

Ring Opening Metathesis Polymerization of Cyclic Olefins by PMe3–Supported (Arylimido)Niobium–Alkylidene Catalysts

Macromolecular Chemistry and Physics, Volume 227, Issue 11, 16 June 2026.
(Arylimido)niobium(V)–alkylidene catalysts containing pentafluorophenylimido ligand, Nb(CHR)(NC6F5)(OC6X5)(PMe3)2 (R = CMe2Ph, X = F; R = SiMe3, X = Cl), show rather low catalytic activity than the 2,6‐dihalophenylimido catalysts, Nb(CHSiMe3)(N‐2,6‐X2C6H3)(OC6X5)(PMe3)2 in ring opening metathesis polymerization (ROMP) of norbornene.

Synthesis and characterization of styrene-co-divinylbenzene-graft-linseed oil by free radical polymerization

eXPRESS Polymer Letters, 2008
A variety of opaque white to light yellow polymeric material have been prepared by two methods, one copolymerization of styrene (ST), divinylbenzene (DVB), and grafting of linseed oil (LIN), and the second involves the copolymerization of the same ...
