Abstract

PURPOSE: To produce a high-MW aromatic polyamide, by reacting an aromatic aminocarboxylic acid with an aromatic diamine in the presence of a phosphorous acid aromatic ester, a tert. amine and halides of Li and Ca.
CONSTITUTION: The following reaction is carried out in the presence of a compound of formulaI, wherein R is OR' or OH or a hydrocarbyl, R' is an aromatic group which may be further substituted, LiX, wherein X is a halogen, and CaX2 or a combination of these members and a tert. amine. Namely, a mixture is polycondensed which contains a compound of formula II, wherein R is an aromatic group, or of formula III, wherein R is a straight, branched or cyclic aliphatic group of an aromatic group, and a compound of formula IV, wherein R is an aromatic group or a group formed by linking at least two such groups through O or SO2.
