Popis:	A series of poly(amide-imide)s has been synthesized by the direct polycondensation of biphenyl imide containing diacids with aromatic diamines using triphenylphosphite (TPP) as the condensation agent in a N-methyl-2-pyrrolidone (NMP)-pyridine solution containing 3.5 wt% LiCl. The direct polycondensation was markedly facilitated to give high-molecular-weight (0.24
