Hydrogen adsorption in microporous hypercrosslinked polymers

Chemical Communications, 2006
A microporous hypercrosslinked polymer resin was synthesized and shown to adsorb 3.04 wt.% hydrogen at 77 K and 15 bar; this represents the highest level of hydrogen adsorption yet observed for an organic polymer.

Positron annihilation in hypercrosslinked polystyrenes

Chemical Physics, 2003
Positron annihilation in hypercrosslinked polystyrene, called CPS(0.3)150E, has been studied as a function of temperature in the range from 35 to 370 K. The positron lifetime spectra were resolved into five components using the PATFIT and MELT programs.

Recent Development of Hypercrosslinked Microporous Organic Polymers

Macromolecular Rapid Communications, 2013
AbstractHypercrosslinked polymers (HCPs) are currently receiving great interest due to their easy preparation, high chemical and thermal stability, and low cost. Combined with the lightweight properties and high surface areas HCPs can be considered as promising materials for gas storage and separation, catalysis, and heavy metal ions removal in ...

Hypercrosslinked cholesterol-based polystyrene monolithic capillary columns

Journal of Chromatography A, 2016
Cholesteryl methacrylate has been used to obtain hypercrosslinked poly(cholesteryl methacrylate-co-4-methylstyrene-co-vinylbenzyl chloride-co-divinylbenzene) monolithic stationary phase for capillary liquid chromatography. Different contents of cholesteryl methacrylate and toluene in polymerization mixture have been tested to obtain chromatographic ...

Hypercrosslinked Ion-Exchange Resins

2011
Publisher Summary This chapter reviews the ion exchange capacity and swelling behavior of hypercrosslinked strong acidic ion-exchange resins. The swelling of hypercrosslinked sulfonated ion-exchanger in nonpolar benzene, heptane, and ethylene dichloride is only insignificantly smaller than that in water or polar methanol.

Hypercrosslinked Polystyrene as Hemosorbents

2011
Publisher Summary Hypercrosslinked polystyrene materials have a sufficiently large portion of pores with smaller diameters and high adsorption capacity of the material toward smaller toxic molecules, and lower affinity to large protein molecules probably due to size exclusion effects. The mechanical strength of these hypercrosslinked polystyrene–poly-

Soluble Intramolecularly Hypercrosslinked Nanosponges

2011
Publisher Summary This chapter introduces a novel macromolecular species, the intramolecularly hypercrosslinked polystyrene (IHPS) or “nanosponge” that differs fundamentally from the four basic types: (1) globular macromolecules, (2) rigid rod-like molecules, (3) flexible and voluminous coils, (4) highly branched (hyperbranched) macromolecules with ...

Highly Porous Hypercrosslinked Polymers Derived from Biobased Molecules

ChemSusChem, 2019
AbstractHighly porous and hyper‐cross‐linked polymers (HCPs) have a range of applications and are typically synthesized in an unsustainable manner. Herein, HCPs were synthesized from abundant biobased or biorelated compounds in sulfolane with iron(III) chloride as Lewis acid catalyst.

Other Applications of Hypercrosslinked Polystyrene

2011
Publisher Summary This chapter discusses several other applications of hypercrosslinked polystyrene. The extraction of rhenium by impregnated hypercrosslinked sorbents is discussed. The consumption of rhenium has been rapidly growing due to its increased use in superalloys in the aircraft and spacecraft industries, and also as platinum–rhenium ...
