Abstract

The samples of poly allyl diglycol carbonate PADC (CR-39) (stored and fresh samples) polymer track detectors have been heated for different annealing temperatures and different annealing times. The thermal stability has been studied for different annealed samples; also it was examined as a function of storage time. The degree of crystallinity percentage has been studied for different annealed samples and stored samples. The samples were etched in 6 M KOH solution at 70°C for 3 h as etchant duration. The variation of bulk etch rate of isochronal annealed samples has been studied. The results indicate an improvement in the thermal stability of Poly allyl diglycol carbonate PADC; where the bulk etch rate increases with the increase in the annealing temperature and annealing time. The storage time has no noticeable effect on the bulk etch rate of un- annealed samples, though the thermal stability of PADC improved with increasing the storage time.
