ABSTRACT:The effects of ␥-radiation on a low-density polyethylene (LDPE) were investigated by novel techniques, such as crystallization analysis fractionation and preparative fractionation, to analyze and compare their performance with other analytical procedures such as DSC, FTIR, and GPC. The LDPE was thus irradiated with four different doses of ␥-radiation. Different fractions were obtained from these irradiated materials by preparative fractionation, which were characterized by the above-mentioned analysis techniques. The changes in the morphology and chemical structure of LDPE after the irradiation were analyzed and it was found that both oxidative scission and crosslinking are phenomena related to the exposure of LDPE at high-energy radiation. Crystallization analysis fractionation and preparative fractionation proved to be suitable techniques to characterize the effects of ␥-radiation on a low-density polyethylene material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
