New N-phenylated aromatic-aliphatic and all aromatic polyamides were prepared by the high-temperature solution polycondensation of 4,4Π-dianilinobiphenyl with both aliphatic (methylene chain lengths of 6 -11) and aromatic dicarboxylic acid chlorides. All of the aromatic-aliphatic polyamides and the
The diamine 1,4-bis(4-aminophenoxy)-2,5-di-tert-butylbenzene, containing symmetric, bulky di-tert-butyl substituents and a flexible ether unit, was synthesized and used to prepare a series of polyamides by the direct polycondensation with various aromatic dicarboxylic acids in N-methyl-2-pyrrolidino
