Synthesis of polyamidines based on 1,4-dicyanobenzene and 4,4 -diaminodiphenyl oxide in ionic liquids

摘要

1,4-Dicyanobenzene and 4,4'-diaminodiphenyl oxide at 190-200 °C in ionic liquids form polyamidines of different molecular weights, whose T_(10%) in air is in the range 250-270 °C.In recent decades, polymers have found wide application in the creation of optical storage media: light-sensitive materials, electrophotographic and photothermoplas-tic recording media.
