Radicals have been detected by electron spin resonance studies.ĮPR technique is used not only for the identification of different radicals or defects but also for Possible radicals that might be produced by irradiation process, the secondary alkyl and the allyl In the past to study radical intermediates generated by irradiation of polyethylene. Of the sample with EPR results, it is possible to correlate the amount of defect generated during the Spectroscopic techniques related to the number of double bonds or to the percentage of crystallinity Quantitative evaluations of radicals themselves.
In this work we used and elaborated EPR results to obtain some new information about the trend Irradiation with the structure of the starting material. Of different radicals vs the amount of irradiation dose. We aimed to stabilizeĪ correlation between structural properties of the materials used and their sensitivity towards Polyethylene samples that differ in crystallinity and number of double bonds.
Two different medical gradeUHMWPES were used as resin powders with a molecular mass higher Irradiation to identify the more stable material even after high dose irradiation.
