Polyethylene radiation-induced structural changes

A BC NMR Study of Radiation-Induced Structural Changes in Polyethylene... [Pg.245]

The problems involved in observing resonances from gelled polyethylene were also encountered in this study. We decided, therefore, to examine polyethylene samples irradiated with absorbed doses less than the gel dose. By so doing, some of the radiation induced structural changes produced prior to gelation could be detected. [Pg.246]

Radiation induced structural changes in polyethylene have been investigated for over 30 years. These studies have shown that the principal chemical changes which occur during irradiation are ... [Pg.264]

The electron irradiation of linear and branched polyethylenes causes several molecular rearrangements in the polymer structure [59]. In addition to the significant changes in the type and distribution of unsaturated groups, IR comparison of the radiation-induced chemical changes that occur in air and in a vacuum showed that oxygen has a marked influence on the structural rearrangements that occur on irradiation. [Pg.326]
