摘要:
New crosslinkable bis-imidyl derivatives are described which can be produced by reaction of imidylphthalic acid derivatives, such as maleimidyl-phthalic acid anhydrides, with monomeric, oligomeric or polymeric diamines. The new crosslinkable bis-imidyl derivatives can be used for producing crosslinked polymers which are distinguished, in particular, by their stability to oxidation and to heat.
摘要:
New imidyl-benzene-dicarboxylic and -tricarboxylic acid derivatives, in particular 5-maleimidyl-trimellitic acid derivatives and 3,5-bis-(maleimidyl)-phthalic acid derivatives, and a process for their manufacture are described. These imidyl-benzene-dicarboxylic and -tricarboxylic acid derivatives are suitable for the manufacture of crosslinkable polymers, above all polycondensation and polymerization products, which are distinguished by good processability and good solubility in customary organic solvents. Imidyl compounds, according to the definition, which have anhydride groups can also be used as curing agents for optionally modified epoxide resins.

摘要:
Crosslinkable mixtures of bis-imidyl derivatives and diamines are described, for example of the bis-imide of 2 moles of 3-maleimidyl-phthalic acid anhydride and one mole of 4,4'-diaminodiphenylmethane and a diamine. These mixtures are characterized by their good solubility in a large number of organic solvents, and they can also be processed from the melt. The crosslinked products obtainable therefrom are distinguished in particular by their good thermooxidative stability.
摘要:
The invention relates to new imidyl compounds of the formula Ia and isoimidyl compounds of the formula Ib ##STR1## IN WHICH A denotes a divalent organic radical, especially an ethenylene, ethylene or propylene group. These compounds serve as curing agents for epoxide resins and give cured products with good mechanical and electrical properties.

摘要:
Crosslinkable mixtures of oligomers or polymers, containing terminal imidyl groups, and diamines are described, for example mixtures of a polyamide oligomer or polyamide-acid oligomer, or terminal polyamide polymer or polyamide-acid polymer, having maleimidylphthalic acid groups, and a diamine. These mixtures and the pre-polymers obtainable therefrom are soluble in customary organic solvents, and in general they can also be processed from the melt. The crosslinked products obtainable therefrom are distinguished in particular by their good thermo-oxidative stability.
