Mutagenicity of vinyl compounds in salmonella typhimurium

Teratogenesis, Carcinogenesis, and Mutagenesis, 1981
AbstractEighteen compounds structurally related to the mutagenic carcinogen vinyl chloride have been tested for mutagenicity in five strains of Salmonella typhimurium. Acrolein, acrolein diethylacetal, acrylonitrile, allyl alcohol, allyl bromide, crotonaldehyde, crotyl alcohol, and vinyl bromide were mutagenic with one or more strains; acrolein ...

Studies on diacetylenic vinyl compounds

Polymer Bulletin, 1989
The copolymerization of maleic anhydride(MAn) with phenyl-4'-vinylp henylbutadiyne(PVPB) was carried out using 2,2'-azobisisobu tyronitrile as an initiator. Although PVPB does not homopolymerize by free radicals in solution, it copolymerized giving copolymers having average molecular weights up to 12,000, and consisting of slightly more PVPB units. The

Nephrotoxicity of Halogenated Vinyl Cysteine Compounds

Journal of Urology, 1982
S-(1,2-dichlorovinyl) cysteine (DCVC), is a potent nephrotoxin. In order to determine if other vinyl cysteine conjugates were nephrotoxic, halogenated vinyl cysteines, HVC-1 and HVC-2, were prepared from chlorotrifluoroethylene (CTFE), a fluorocarbon monomer, or chlorotifluoroethylene, a metabolite of halothane, respectively. Three days after receiving

Reprocessing of Medical Vinyl Compounds

Journal of Vinyl and Additive Technology, 1996
Abstract There is increasing public concern over the disposal of plastic waste. The escalating cost of vinyl compounds would also make it desirable to reuse unavoidable process waste and surplus devices, not only in lower value markets, but also for medical device end users.

Topochemical polymerization of vinyl compounds

Radiation Physics and Chemistry (1977), 1980
Abstract The present situation of the solid state polymerization is subject to considerations according to those principles that were layed down by Prof. Michel Magat in his publication, entitled Polymerization in the Solid State ( Polymer , 1962, 3 , 449–463).

Vinyl compounds of heavy metals

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1958
1. Mono- and di-vinyl compounds of mercury and thallium and divinyl compounds of tin were synthesized. 2. An investigation was made of the reactions of divinylmercury with lithium, mercury salts, and thallium salts and also of the reactions of divinylthallium halides with mercury and with tin and thallium halides.

Rotational isomerism in vinyl compounds

Journal of Molecular Structure: THEOCHEM, 1984
Abstract The conformational potential of propene, 1-butene, vinyl alcohol and methyl vinyl ether was calculated with the PCILO algorithm. A potential energy function composed of nonbonded (Lennard-Jones 6–12 plus Coulomb) and torsional contributions was fit to quantum mechanical energies.

Studies on diacetylenic vinyl compounds

Polymer Bulletin, 1986
Synthese a partir de l'ethynyl-4 styrene et du phenyl bromoacetylene. Polymerisation lente avec l'AJBN en solution; a l'etat fondu, a 80°C, obtention d'un polymere insoluble. L'irradiation UV du cristal conduit a des polymeres solubles et insolubles. A −78°C, dans le THF, en presence de n-butyllithium, obtention de poly(p-phenylbutadiynyl styrene)

Compound requirements for vinyl siding

Journal of Vinyl Technology, 1979
Abstract Basic principles of good compounding for weatherable vinyl siding are discussed. Appropriate level of stabilizer is such that 50 percent of initial should remain after the extrusion process. Balanced lubrication is necessary. Judicious choice of pigments and impact modifiers is called for.

The Crosslinking of Ethylene-Vinyl Acetate with Organometallic Compounds

Journal of Macromolecular Science, Part A, 1990
Abstract Organometallic compounds such as aluminum trialkyl (AIR3) and lithium alkyl react nonradically with ethylene-vinyl acetate copolymers (EVA) to yield very high crosslinking rates. The mechanism is characterized by simultaneous reactions: addition, reduction, and enolization accompanied with ethene and ethane elimination.
