To determine the rate of macromolecular scission accompanying the photo-initiated crosslinking of polyethylene, a method was applied which consists in plotting sol fraction vs. time in the log-log coordinates. The slopes showed the backbone scission to accompany crosslinking. With the most effective photo-crosslinking initiator, 2-ethylanthraquinone, the scission rate was found to be 2.6 times the crosslinking rate.
