New polymers for solid state nuclear track detection

Two novel polymers have been prepared from a monomer N-allyloxycarbonyl diethanolamine-bis(allyl carbonate) i.e., NADAC by cast polymerization and were successfully used as solid state nuclear track detectors for α particles and fission fragments. The homopolymer PNADAC was prepared by IPP catalyzed polymerization of NADAC. A copolymer of NADAC with allyl diglycol carbonate (ADC) called poly-[(NADAC)-co-(ADC)] was also prepared similarly. A preliminary study on the etching conditions and track detection characteristics of the newly developed materials was carried out. It was found that the copolymer is more sensitive to α particles as compared to commercially available PM-250™ track detector.
