Ionic reactions in pulse irradiated poly(vinyl chloride) film—the effect of plasticizers

Poly(vinyl chloride), PVC + plasticizer (DEHP, TOTM) films were pulse irradiated using electron accelerator and the transient species generated in these matrices were analysed. The absorption spectra of plasticizers ions (anion and cation type) were identified in PVC system using as a model 2-propanol and sec-butyl chloride solutions of respective plasticizers. The mechanism of reactions is proposed and discussed.
