The pulse radiolysis studies of poly(vinyl chloride), PVC, film containing stabilizers i.e., Tinuvin P, Irgastab PVC 11, and Irganox 1076 have been carried out with the main aim of investigating ionic reactions in these systems. The evidences are presented concerning the formation of ionic transients in model solvents i.e. 2‐propanol and sec ‐butyl chloride as well as in PVC film. In PVC‐stabilizer system under consideration the additives can contribute to the positive charge transfer processes whereas Tinuvin P, in addition may scavenge effectively electrons (the rate constant for e − solv scavenging in 2‐propanol equals 5.9 × 10 9 mol −1 dm 3 s −1 ) influencing the negative charge scavenging by PVC matrix itself and the HCl formation during the radiolysis of PVC. © 2007 Wiley Periodicals, Inc.
