“…The abscissa is the dimensionless ratio, rg/r, where rg is the dose to the gel point. The Charlesby-Pinner equation expressed in dimensionless units is s + s'A = (7 ) + {2 -(Vi)X}(re/r) (7) where X is the ratio of the G value for chain scissions, G{S), toG(X), the cross-linking G value. Also plotted in Figure 6 are the data of Kang, Saito, and Dole.12 The agreement between the two sets of data is probably within the experimental limits of accuracy.…”

Freeze‐dried chain folded single crystals and the single crystals without amorphous surface layers (crystalline cores) of different thicknesses of linear polyethylene were irradiated with 60Co γ‐rays up to 600 Mrad. Concentration of trans‐vinylene double bonds and conjugated diene produced during irradiation of the crystals was measured by infrared. Concentrations of trans‐vinylene and of the conjugated diene were independent of thickness of crystalline core which suggest that the double bonds wer randomly distributed in the crystalline parts of the crystals. Concentrations of trans‐vinylene and of conjugated double bonds were lower in chain‐folded crystals than in the crystalline cores and this suggests that the folds (amorphous surface layers) are less preferential sites for formation of the double bonds. The zero‐order growth and first‐order decay kinetics of trans‐vinylene double bonds was studied by the equation derived by Dole et al1. The equation is strictly obeyed up to 300 Mrad and the results then deviate. Since there is the decay of trans‐vinylene double bonds and though there are no crosslinks in the crystalline cores, it has been suggested that the decay of the double bond does not result in the crosslinks.
