Journal of Polymer Science: Polymer Chemistry Edition, 1981
Abstract13C‐NMR spectroscopy was used in a detailed study of vinyl chloride‐vinyl acetate and vinyl chloride‐vinyl propionate copolymers. The NMR spectra of the methylene carbon region showed three split peaks whose intensities changed with composition of the copolymers.

Vinyl Chloride-Vinyl Bromide Copolymers
Journal of Macromolecular Science: Part A - Chemistry, 1973Abstract Radical copolymerization kinetics of vinyl chloride (VC) and vinyl bromide (VB) lead to the following reactivity ratios rVC=0.825 rVB=1.05 Vinyl bromide acts as a chain transfer agent, more powerful than vinyl chloride, the transfer constant for VC radicals being 8.5 × 10−3 at 40° C.

Pediatrics, 1974
A 1½-day international symposium was held in New York primarily on liver disease from heavy industrial exposure to vinyl chloride. Worldwide, 19 workers are known to have developed hepatic angiosarcoma: 13 in the United States, two in West Germany, two in Sweden, and one each in Great Britain and Norway.

Vinyl Chloride-Associated Disease
1981The history of vinyl chloride-associated disease, its recognition and prophylaxis is a classic example of shutting the stable door after the horse has bolted. It should help to emphasize the need to shift our attention to preventing exposure from occurring rather than to reparative measures.

Carcinogenicity of vinyl chloride and vinylidene chloride
Journal of Toxicology and Environmental Health, 1978Exposure of mice to 50, 250, or 1000 ppmm of vinyl chloride (VC) in the air for 6 h/d, 5 d/wk, caused a high incidence of bronchioloalveolar adenoma, mammary gland tumors, and hemangiosarcoma. Mammary gland tumors occurred in the females and included ductular adenocarcinoma and squamous and anaplastic cell carcinomas with metastasis to the lung ...

Vinyl pinonate‐vinyl chloride copolymers
Journal of Polymer Science, 1959AbstractA homopolymer of vinyl pinonate and copolymers of vinyl pinonate and vinyl chloride have been described. The copolymer containing 19.8% of vinyl pinonate seems to show the best all around properties as a rigid plastic. The presence of vinyl pinonate as a component of the copolymer does not give a plasticized film.

Pharmacokinetics of vinyl chloride
General Pharmacology: The Vascular System, 1978Abstract So far, all studies on pharmacokinetics of vinyl chloride in vivo used rats. Consistent evidence shows that, above a concentration of “saturation” which on inhalation exposure is reached at about 250 ppm vinyl chloride in the atmosphere, non-linear (dose-dependent) pharmacokinetics apply.

The solubility of vinyl chloride in poly(vinyl chloride)
Die Angewandte Makromolekulare Chemie, 1975AbstractThe solubility of vinyl chloride monomer (VCM) in PVC powders has been studied by equilibrium vapor pressure and microbalance gravimetric techniques at temperatures from 30 to 110°C. At temperatures and VCM concentrations above the glass transition, the solubility closely follows the Flory‐Huggins equation with χ = 0.98 and is independent of ...
