A series of new AB-type poly(etherimide)s having bisphenol-type moiety was prepared by the one-pot polyimidization using triphenylphosphite(TPP) in N-methyl-2pyrrolidone(NMP)/pyridine solution at 150Β°C. Complete cyclodehydration was observed in the polymerizations as well as in model reactions. Poly
Bis(4-oxybenzoic acid) tetrakis(phenoxy) cyclotriphosphazene 4,6,3,5,2l 5 ,4l 5 ,6l 5 -triazatriphosphinin-2-yl]oxy-benzoic acid) was synthesized and direct polycondensed with diphenylether or 1,4-diphenoxybenzene in Eaton's reagent at the temperature range of 80-120ΠC for 3 hours to give aromatic p
