Crosslinkable polymers prepared from maleimidyl substituted trimellitic acid compounds

Claim 1

A crosslinkable polymer which has an average molecular weight of at least 1,200, or the corresponding cyclized imide derivative, which is manufactured by reacting at a temperature between about -50° and 300° C. in the melt or in an inert organic solvent or solvent mixture 0.5 to 100 mol % of a compound of the formula Ib or IIb ##STR20## and 0 to 99.5 mol % of a compound of the formula IV ##STR21## with substantially stoichiometric amounts of a compound of the formula V HY -- Q -- XH (V) in which formulae m and n independently of one another represent the number 1 or 2, A represents a radical of the formula ##STR22## R 2 ' represents 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 with 1 to 18 carbon atoms or the two R 2 's conjointly represent the --O-- grouping, R' 1 represents a chlorine atom, 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; or alkoxy of 1 to 18 carbon atoms, M + represents an alkali metal cation, a trialkylammonium cation with 3-24 carbon atoms or a quaternary ammonium cation, R 3 and R 4 independently of one another represent hydrogen, chlorine or bromine, X and Y independently of one another represent ##STR23## and R 5 = hydrogen, alkyl with 1-4 carbon atoms or phenyl, Q represents an aliphatic radical with at least 2 carbon atoms or a cycloaliphatic, araliphatic, carbocyclic-aromatic or heterocyclic-aromatic radical, or --Y--Q--X represents the grouping ##STR24## R 6 and R 7 independently of one another represent hydrogen, methyl or phenyl and Q 1 represents an aliphatic radical or a cycloaliphatic, carbocyclic-aromatic or heterocyclic-aromatic radical, in which the carbonyl and carboxyl groups are bonded to different carbon atoms and the carboxyl groups are each in the ortho-position relative to a carbonyl group, M 1 represents a chlorine atom, 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; or alkoxy with 1 to 18 carbon atoms, or when m or n is 2, M 1 , conjointly with M 2 , forms the --O-- grouping and the groups --COM 1 and --COM 2 are bonded to different carbon atoms and the --COM 1 groups are each in the ortho-position relative to a --COM 2 group.
