Gas emission from chlorinated polymers induced by synchrotron radiation

Chlorinated polymers, poly(vinyl chloride) (PVC), poly(vinylidene chloride) (PVDC), and ethylene-chlorotrifluoroethylene copolymer (E-CTFE) have been irradiated with white light from the Brazilian synchrotron light source (LNLS). The volatile products generated by the interaction of the polymers wit...

description Chlorinated polymers, poly(vinyl chloride) (PVC), poly(vinylidene chloride) (PVDC), and ethylene-chlorotrifluoroethylene copolymer (E-CTFE) have been irradiated with white light from the Brazilian synchrotron light source (LNLS). The volatile products generated by the interaction of the polymers with the photons were analysed by mass spectrometry and their intensities studied as a function of the photon flux. The results show that HCl, the most intensely emitted gas, may be used as an indication of the sensitivity of the polymers to the radiation. Among the polymers investigated, PVDC was found to be the most sensitive to white light.
