Process for the preparation of poly-o-hydroxyamides and poly-o-mercaptoamides

The prodn. of poly-o-hydroxyamides or poly-o-mercapto-amides (I) comprises reacting a bis-o-aminophenol or bis-o- aminothiophenol (II) with a dicarboxylic acid ester of formula G-O-CO-R*-CO-O-G (III), in which G = a gp. of formula (G-1) or (G-2), where: R1 and R2 = H, F, CH3 or CF3; and R* = (CR2)m...

Zusammenfassung:	The prodn. of poly-o-hydroxyamides or poly-o-mercapto-amides (I) comprises reacting a bis-o-aminophenol or bis-o- aminothiophenol (II) with a dicarboxylic acid ester of formula G-O-CO-R-CO-O-G (III), in which G = a gp. of formula (G-1) or (G-2), where: R1 and R2 = H, F, CH3 or CF3; and R = (CR2)m or one of the gps. (i)-(xiii). In the formulae: R = H, F, CH3 or CF3; m = 1-10; A = (CH2)n, (CF2)p, CMe2, C(CF3)2, CMePh, C(CF3)Ph, C(CF3)C6F5, CPh2, CF2-CF(CF3), CH=CH, CF=CF, C IDENTICAL C, O-C6H4-O, O, S, CO or SO2; n = 0-10; p = 1-10; X = CH or N; T = CH2, CF2, CO, O, S, NH or NMe; Z1 = CH2 or CHMe and Z2 = CH or CMe, or Z1 = CH2 or CHMe and Z2 = N, or Z1 = NH or NMe and Z2 = CH or CMe, or Z1 = NH or NMe and Z2 = N; Z3 = CH, CMe or N; and Z4 = O or S; and all the H atoms in any of the aromatic gps. may be replaced by F.
