摘要：

Different linear low density polyethylenes (LLDPEs) based on hexene and butene comonomer were irradiated with gamma-rays under air. The oxidation products have been quantified using NO and SF4 treatments by IR spectroscopy. An FTIR examination displayed unexpected products such as free hydroperoxides and trans-vinylenes. It was found that the type of alpha-olefin used to process LLDPE films may influence the mechanism of oxidation. Parameters such as the melt index and the density seem to affect the gamma-oxidation rate.
