Sorption properties of hypercrosslinked polystyrene sorbents

Reactive Polymers, Ion Exchangers, Sorbents, 1983
Abstract Sorption properties of a new type of nonspecific sorbent—hypercrosslinked polystyrene—with respect to vapors of organic solvents (alkanes, acetone, methanol) and water have been studied. The sorption capacity of the hypercrosslinked sorbent is shown to be many times greater than that of conventional organic and inorganic porous sorbents. The

Heterogeneous membranes filled with hypercrosslinked microparticle adsorbent

Reactive and Functional Polymers, 2005
Abstract Synthesis of hypercrosslinked microparticles is described and the effect of reaction conditions on adsorbent properties is discussed. Heterogeneous membranes based on hypercrosslinked microparticle adsorbent with a poly(phenylene oxide) binder were prepared and tested for separation of hydrogen from a isobutane/hydrogen mixture.

Magnetic nanocomposites based on hypercrosslinked polystyrenes

Bulletin of the Russian Academy of Sciences: Physics, 2009
Magnetic sorbents (composites with inclusions of iron oxide nanoparticles in a polymer matrix), which can be used to remove toxic compounds by the magnetic separation method, have been developed on the basis of hypercrosslinked polystyrenes. Composites based on gel-type hypercrosslinked polystyrenes contain nanoparticles with a radius of ∼3 nm, while ...

Hypercrosslinked Polymers Preparation VS Methylene Blue Adsorption

Materials Science Forum, 2013
In the study, two kinds of hypercrosslinked polymers were prepared by polymerization of dichloromethyl aryl monomer with benzene or itself. The chemical and pore structure of above polymers were characterized by FT-IR and BET. The results showed that these polymers possessed high BET specific surface area (up to 1000 m2/g) and large pore volumes (up to

Hypercrosslinked polystyrene: The first nanoporous polymeric material

Nanotechnologies in Russia, 2009
The principles of synthesis—the structural and distinctive features of hypercrosslinked polysty rene—are described. The material is obtained by intensely crosslinking the solvated polystyrene chains with rigid bridging spacers. The resulting singlephase op enworked elastic network can be considerably deformed upon swelling or the application of an ...

Solid-state13C-NMR analysis of hypercrosslinked polystyrene

Journal of Polymer Science Part A: Polymer Chemistry, 1997
Hypercrosslinked polystyrenes, synthesized by reaction of linear or lightly crosslinked polystyrene with chloromethyl methyl ether (CME) and a Lewis acid in a good solvent, swell even in nonsolvents for polystyrene. Structures and dynamics of hypercrosslinked polystyrenes in both dry solid and solvent-swollen gel states have been determined by 13 C-NMR

Tailoring the pore size of hypercrosslinked polymers

Soft Matter, 2011
We report here a practical method to tailor the pore size of hypercrosslinked poly(divinylbenzene-co-vinylbenzyl chloride) (HCP-DVB-VBC) by adjusting the DVB content in poly(divinylbenzene-co-vinylbenzyl chloride) (DVB-VBC) precursors, and then hypercrosslinking these DVB-VBC precursors. With the DVB content varying from 0–10%, the pore size of HCP-DVB-

Multi‐stimuli‐responsive hypercrosslinked microporous polymeric adsorbent

Journal of Polymer Science
AbstractIt is challenging but of practical meaning to provide adsorbents with multiple responsive properties. Here, we report an intelligent microporous polymeric adsorbent constructed by block copolymer‐grafted microporous polymer nanospheres. With its multi‐stimuli‐responsive functions, the adsorbent shows rapid fluorescent response to temperature ...

Adsorption of 4-Chlorophenol onto Hypercrosslinked Resins

Advanced Materials Research, 2011
Two kinds of hypercrosslinked resin ZH-01 and ZH-03 were prepared in this study. Experimental investigations were conducted to study the adsorption characteristics of 4-chlorophenol on the hypercrosslinked resins by method of static adsorption. The equilibrium adsorption data was fitted to Freundlich adsorption isotherm model to evaluate the related ...
