A study was made of the solubility of irradiated polyethylene. The experimental data were treated according to the Saito‐Inokuti theory for gel formation in polymers exposed to ionizing radiation. Among other things, this theory is based upon the molecular weight distribution of the unirradiated polymer; in the present work, the actual distributions were determined by high‐temperature gel permeation chromatography and corrected for long‐chain branching. Under these circumstances, good agreement between theory and experimental data was obtained, which allowed the determination of the radiation yield of main‐chain scission and crosslinking.
