| Positron lifetimes measurements in pure poly(vinyl chlorate) (PVC) and in plastified PVC were performed. Three different plasticizers were used: dibutyl phtalate, dioctyl phtalate and tricresyl phosphate. The measured samples were prepared of PVC with two different plasticizers concentration (20% and 30% of the plasticizers in the poly(vinyl chlorate)). All the measurements were performed in air at room temperature. A conventional fast-slow coincidence lifetime spectrometer was used for the measurements. Free volume radii were calculated from the lifetime data. |
