The Configuration, Conformation and Degradation of Polyvinyl Chloride
The proton spectrum of poly(vinyl chloride) prepared by free-radical polymerization has been studied at 220 MHz and interpreted in terms of pentads for the x-protons and tetrads for the n-protons. The chemical shifts are in good agreement with those reported elsewhere using selectively deuterated polymers. The magnitudes of the vicinal coupling constants indicate that in the solvents employed, ...
متن کاملThermal Degradation of Polyvinyl Chloride
A survey is given of the recent advances in the study of and the present knowledge of the thermal degradation of polyvinyl chloride. The sites for initiation of the thermal degradation, the mechanism of the dehydrochiorination, the discolouration of PVC by heat and the influence of plasticizers on the rate of degradation are discussed.

متن کاملIncidence of cancer among vinyl chloride and polyvinyl chloride workers.
The results of a follow up study of the incidence of cancer and the mortality in a cohort of 454 male workers producing vinyl chloride and polyvinyl chloride are presented. The study population was restricted to employees with more than one year's work experience in the study plant between 1950 and 1969 and the cohort was followed up from 1953 to the end of 1979. Twenty three new cases of cance...
