Abstract

Ultraviolet irradiation of polyethylen, nylon, Mylar, and Acrilan produces higher scission‐to‐crosslinking ratios when irradiation is performed in a nitrogen atmosphere than it does when irradiation is in a vacuum. Irradiation of polyethylene in nitrogen causes a sharp decrease in molecular weight while irradiation of Acrilan in vacuum causes an equally notable increase in molecular weight.
