Thermophysical properties and reaction kinetics of γ-irradiated poly allyl diglycol carbonates nuclear track detector

Kinetic thermogravimetric technique was used to study the effect of gamma irradiation on the poly allyl diglycol carbonates ( PADC) within the dose range from 50 to 3 x 106 Gy. The approach of Coats-Redfern was used to analyze the data. Results showed that low doses around 50 Gy make the polymer slightly more resistive to heat treatment. Higher radiation doses cause severe effects in the samples accompanied by the formation of lower molecular mass species and consequent crosslinking. Results support the domination of re-polymerization and crosslinking for the. radiation interaction PADC at dose below about 1 x 103 Gy, while the situation is inverted above 1 x 103 Gy in which chain secession dominates.
