Synthesis and properties of polyamides with diphenylene anthracene fragments in the macromolecules

Abstract

The patterns of low temperature polycondensation of 9,10-bis-(4′-aminophenyl)anthracene and terephthaloyl chloride in amide solvents have been studied. High molecular weight homo-and co-polyamides have been obtained based on 9,10-bis-(4′-aminophenyl)antracene, p-phenylene diamine, 9,9-bis-(4′-aminophenyl)fluorine, 5(6)-amino-2(4′-aminophenyl)benzimidazole and the chloranhydrides of adipic, sebacic, tere- and iso-phthalic acids, 2,2-bis-(4-carboxyphenyl)hexafluoropropane and 3,3-bis-(4′-carboxyphenyl)phthalide. Strong films have been obtained from homo- and co-polyamides soluble in amide solvents.
