摘要：

It has been shown previously that linear polyethylenes undergo increases in crystallinity and peak melting temperature after irradiation, the magnitude of the effects being dependent upon the dose and the molecular weight of the polymer. The crystallinity was also found to increase with time after irradiation (aging) up to 112 months, although peak melting temperature declined slowly with aging time. The results were explained in terms of the scission of tie. © 1990, Taylor & Francis Group, LLC. All rights reserved.
