New aromatic poly(amide-ether)s (II) have been synthesized by solution polycondensation of various aromatic diamines having two ether bridges (I) with a diacid chloride containing silicon, namely bis(chlorocarbonylphenyl)-diphenylsilane. These polymers are easy soluble in polar amidic solvents such
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 80-120ЊC for 3 hours to give aromatic p
## Abstract Four aromatic diamines containing aliphatic spacers and __Meta__ and __para__ oriented oxyphenylene rings, and their corresponding hydrochlorides, were combined with isophthaloyl chloride (IPC) and terephthaloyl chloride (TPC) to give high molecular weight polyamides by interfacial and
