Notes:
Equal radiation yields of hydrogen are obtained from bulk polyethylene and thin films of solution crystallized polyethylene, with a G value of 4.6. The corresponding value for very thick mats of the solution crystallized material is 3.4. Reasoning from material balance considerations indicates that the yield of radiation-induced crosslinking for bulk and thin films is about twice that for thick mats of polyethylene. It is suggested that thin films and thick mats differ only in fold surface contact, and that crosslinking is preferential at the folds. The retention of xylene between fold surfaces following crystallization is compatible with the effect of irradiation on trapped solvent.
