Spectroscopic studies, phonon dispersion and heat capacity of poly (vinylidene chloride)

Carcinogenicity studies on vinylidene chloride.

Results of a study on Wistar rats regarding a possible carcinogenic effect of vinylidene chloride (VDC) were presented previously by one of the authors. Due to the unclear character of these results, a second inhalation study was initiated with Sprague-Dawley rats. Groups of 60 animals were exposed to 100 and 75 ppm VDC, along with one control group. A final report on the pathological results m...

Vibrational spectroscopic characterization of form II poly(vinylidene fluoride)

The Fourier transform Raman (FT-Raman) and infrared absorption (FTIR) spectra of form II poly(vinylidene fluoride) have been recorded and analysed. A complete spectral analysis, assignments to observed bands, normal coordinate analysis and discussion of the spectra are presented. The computed spectrum is in excellent agreement with experiment. The potential energy distribution (PED) is evaluate...

Pharmacokinetics of vinylidene chloride.

Dear Sir: The recent article by McKenna et al. (1) on phar-macokinetics of vinylidine chloride (VDC) in the rat has evoked a number of thoughts. These relate both to one detail of data presentation from the excellent experimental studies and to the general role of pharmacokinetics in supporting risk assessment from high dose studies in mammals. The detail concerns Figure la (Figure 2 of the McK...

ESR Studies of Fast Electron Irradiated Ferroelectric Poly(Vinylidene Fluoride)

Radiation-induced functionalization of ferroelectric poly(vinylidene fluoride) was studied by ESR spectroscopy. The samples were irradiated in the high vacuum of a Van de Graaff accelerator with 1.0 MeV and 1.5 MeV electrons at room temperature and the decay of free radicals was studied after transferring the samples into the air. The samples exhibit a multicomponent ESR spectrum that can be de...
