As illustrated in Figure 3, 2% divinylbenzene
crosslinked Merrifield resin was allowed to react with 2 under [S.
HSE has published chemical hazard alert notices (CHANs) for nine of the 16 withdrawn OESs to help employers control exposure: divinylbenzene
(mixed isomers), furfuryl alcohol (FA), glycerol trinitrote, nitrogen dioxide, nitrogen monoxide, sulphur dioxide, ethylene dinitrate, subtilisins and sulphuric acid.
cell diameter [approximately equal to]12 [micro]m)--and four size categories of polystyrene divinylbenzene
plastic spheres--2 [micro]m, 20 [micro]m, 30 [micro]m, and 40 [micro]m--for feeding observations.
Absolute ethanol, ammonia solution, maleic acid anhydride (MAA), divinylbenzene
(DVB), and N-methyl-2-pyrrolidone (NMP) were used as received without further purification.
5- to 15-wt% olefin monomer such as styrene, divinylbenzene
, and alpha methylstyrene, and 0.
This non ionic crosslinked Divinylbenzene
Copolymer adsorbs hydrophobic molecules of low molecular weight (like valerenic acids) from polar solvents.
An absorbent-polydimethylsiloxane (PDMS) solid phase microextraction (SPME) fiber was the more appropriate fiber for extracting beef flavors as compared to a divinylbenzene
Highly porous polymers are prepared by copolymerizing styrene and divinylbenzene
(DVB), resulting in the formation of very small micropores as a result of DVB tying together linear chains of styrene at various points.
polymers, templated resins, or porous carbons.
These terpolymers [1,3] are prepared like butyl rubber with the major exception that a third monomer, bifunctional divinylbenzene
, DVB, is added during the polymerization in the reactor.
For example, N-vinylpyrrolidone copolymer with divinylbenzene
is widely used as a sorbent in solid phase extraction, to determine phenoxy alkanoic acids and other herbicides in water and in the environment .
Coquart and Hennion correlated log k and log P for PGC, C18-silica and polystyrene divinylbenzene
(PS-DVB), as part of their study of the use of Hypercarb as an adsorbent for removing polar contaminants from water samples.
