New polymers for solid state nuclear track detection

摘要

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 alpha 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 a particles as compared to commercially available PM-250 (TM) track detector. (c) 2005 Elsevier Ltd. All rights reserved.
