Heavy-ion Tracks in Polycarbonate - Comparison With a Heavy-ion Irradiated Model-compound (diphenyl Carbonate)

摘要: The chemical modifications induced by energetic heavy ion irradiation of polycarbonate (PC) film are determined GPC, HPLC, ESR, TGA, IR and UV spectrophotometry. main results the creation radicals, chain scission, cross-linking appearance new groups in polymer chain. As far as is concerned, they means a model compound PC: diphenyl carbonate (DPC). following compounds identified after DPC: salicylic acid, phenol, 4,4'-biphenol, 2,4'-biphenol, 2,2'-biphenol, 4-phenoxyphenol, 2-phenoxyphenol, phenyl ether, benzoate, salicylate, 2-phenylphenol 2-phenoxyphenyl benzoate. A similarity between heat treatment has also been established with DPC. On basis these results, we try to give an explanation preferential attack along tracks irradiated film. Also, well-known beneficial effect exposition on selectivity this suggested.
