Crosslinkable mixtures of oligomers or polymers and diamines

Claim 1

A crosslinkable mixture, essentially unpolymerized and stable at temperatures up to about 100° C., consisting of at least one oligomer or polymer of the formula Ia or Ib ##STR15## where in formula Ia the ##STR16## groups independently of each other are linked to the benzene rings in the 3- or 4- position; and a carbonyl of the --COQZ a QOC-- moiety and a --COR group are attached in pairs to adjacent carbon atoms at the 1- and 2- positions of the benzene rings, whereby on each benzene ring one of said carbonyl and --COR groups can be in the 1-position and the other in the 2- position; or of a corresponding cyclised derivative, and of at least one diamine of the formula II hq -- z.sub.2 -- qh (ii) whereby the molar ratio of oligomer or polymer of the formula Ia and/or Ib, or of a corresponding cyclised derivative, to diamine of the formula II is between about 1.2:1 and 50:1, and wherein the X's independently of one another represent hydrogen or, if the radical ##STR17## is in the 4-position of the benzene ring, also --COR 2 , the R's and R 2 's independently of one another represent a hydroxyl group, phenoxy; phenoxy substituted by one or two nitro groups, by one alkyl of 1 to 2 carbon atoms, by one alkoxy of 1 to 2 carbon atoms or by two to five halogen atoms; alkoxy of 1 to 18 carbon atoms or an O - M + group, the R 1 's independently of one another represent a hydroxyl group, phenoxy; phenoxy substituted by one or two nitro groups, by one alkyl of 1 to 2 carbon atoms, by one alkoxy of 1 to 2 carbon atoms or by two to five halogen atoms; alkoxy of 1 to 18 carbon atoms or an O - M + group, or two adjacent R 1 's together represent the --O-- grouping, the A s independently of one another represent a radical of the formula ##STR18## R 3 and R 4 independently of one another represent hydrogen, chlorine, bromine or methyl, M + represents an alkali metal cation, a trialkylammonium cation having 3-24 carbon atoms, or a quaternary ammonium cation, a represents a number from 1-100, m and n independently of one another represent the number 1 or 2, the Z's and Z 2 's independently of one another represent an aliphatic radical having at least 2 carbon atoms, a cycloaliphatic, carbocylic-aromatic or heterocyclic-aromatic radical, the Q's represent --NH--, or --Q--Z--Q-- or --Q--Z 2 --Q-- represent the grouping ##STR19## the Z 1 's represent an aliphatic radical having at least two carbon atoms, or a cycloaliphatic, carbocyclic-aromatic or heterocyclic-aromatic radical, in which the carbon-amide groups and carboxyl groups are bound to different carbon atoms, and the carboxyl groups, if Z 1 represents a cyclic radical and at least one of m and n represetns the number 2, are each in the ortho-position with respect to a carbonamide group, and R 5 and R 6 independently of one another represent hydrogen, methyl or phenyl.
