Vitamin E concentration profiles of unirradiated (a), 65-kGy irradiated (b) and 100-kGy irradiated (c) UHMWPE doped at 120°C for 2 and 24 hours. The vitamin E profiles measured via FTIR (n=3 samples) are shown as individual data points; the predicted vitamin E concentration profile using Eqs. 2 and 3 is shown as the solid line.
