Various crosslinked poly(4-vinylpyridine)s (3) having different degrees of crosslinking were prepared by the radical copolymerization of 4-vinylpyridine (1) with N,N′-hexamethylenediacrylamide (2) as a crosslinker. These crosslinked polymers were examined for their ability to bind methyl orange at...
Most stable latex with narrow size distribution was obtained when BA/4VP ratio was 1/4(g/g). 展开 关键词: Soapless emulsion polymerization Poly(4-vinylpyridine-co-butylacrylate) latex Particle morphology Zeta potential 被引量: 6 年份: 2001 ...
Poly(4-vinylpyridine) (PVP) was crosslinked with 1,4-dibromobutane with a metal ion as template. The adsorption behavior of copper, cobalt, zinc, and cadmium ions on the obtained resin (DBQP) was studied. The DBQP resin prepared with a metal ion as template preferentially adsorbed the metal...
Glucose-permeable poly(ethylene glycol)diglycidyl ether (PEGDGE)-crosslinked electron-conducting redox hydrogels of Os2+/3+ complex-comprising polymers with poly(N-vinylimidazole), and partially N-alkylated poly(4-vinylpyridine) backbones have been studied extensively. See Heller, A. CURRENT OPINION ...
N-vinyl-2-methylimidazole, and 2- and 4-vinylpyridine, 2- and 4-allylpyridine, and the salts thereof.Suitable monomers d) are also alkylallylamines and allylammonium salts, such as diallylmethylamine and diallyidimethylammonium chloride (DADMAC)....
Meanwhile, poly (hydroxyl ethyl acrylate) [23], poly (oxyethylene methacrylate) [24], and 4-vinylpyridine [25] have also been grafting to the PVDF-CTFE to obtain the corresponding amphiphilic copolymer membranes. Liu et al. [26] had prepared PVDF-CTFE hydrophobic porous membranes by NIPS, ...
4-Vinylpyridine copolymers for improved LC–MS tryptophan and kynurenine determination in human serum Tryptophan (an essential amino acid) and its clinically important metabolite—kynurenine contribute to several fundamental biological processes and methods...

4. porous, pearl-shaped cellulose derivatives. SU 732207 describes sorbents produced from activated charcoal and coated activated charcoal, e.g. with a solution of poly(acrylic acid) or poly(acrylic acid) and poly(ethylene amine). Further polymer coatings of activated charcoals are described in...
Crosslinked bead polymers containing vinylpyridine units were prepared by pearl copolymerization of monomer mixtures containing various percentagesof 4-vinylpyridine, styrene, and di-vinylbenzene. The polymers were functionalized by reaction with hydrogen bromide and bromine, and the resulting poly-(vinyl...
