Although this works for many monomers, styrene and divinyl
benzene, alone or with a porogen, are preferred.
As such, a Restek Q-bond, 100 percent divinyl
benzene porous layer open tubular, 30-m, 0.
A gel permeation chromatograph (Model 500, Analytical Scientific Instruments, USA) with a refractive index detector (RI2000, Schambeck, Germany) and two Jordi gel divinyl
benzene mixed bed (Jordi FLP, USA) columns were used to measure the molecular weight relative to the polystyrene standards at 30[degrees]C.
Fukuda, "Nitroxide-Controlled Free-Radical Copolymerization of Vinyl and Divinyl
In an alternative embodiment, the polymer comprises vinyl functional polydimethyl siloxane, and preferably high molecular weight methyl divinyl
siloxane, with or without phenyl substituted siloxane.
occur in the divinyl
(DV) form, namely 8-desethyl, 8-vinyl chlorophyll a (chl [a.
2000) obtained for epoxy-based divinyl
ester and epoxy fumerate resins, respectively.
5) Modified by some hydroxyl-containing compounds, the melting point of aliphatic urethane divinyl
ether crystalline monomer can be decreased to around 75-90[degrees]C, which is suitable for UV-curable powder coatings.
The use of divinyl
sulfone (DVS) as the linker arm molecule for forming cyclosporine and cyclosporine metabolite protein conjugate immunogens is described.
The novel agarose was activated by methods known before: using cyanogen bromide [45, 46], divinyl
sulphone , 1,1'-carbonyldiimidazole , active dyes , and some others (Table 1).
The researchers used a cheap, industrial solvent called divinyl
sulfone that can be bought by the gallon and has been used for decades as an adhesive.
With this in mind, divinyl
terminated PDMDPS was chosen as the basis for the development of the desired polymer.
