Methods and compositions for producing polyimide adhesive bonds |
摘要 |
Methods and compositions for producing imide precursors and polyimide coating and adhesives. Basically a mixture of an oxoimine such as caprolactam, a dianhydride such as 3,3', 4,4'-benzophenone tetracarboxylic acid dianhydride and a solvent such as dimethyl formamide is heated to a temperature of about 60 DEG to 120 DEG C. for a suitable period, then the mixture is cooled and a suitable diamine is added to produce the imide precursor. This mixture may be dried to a powder form or may be used directly as a coating or adhesive. The final polyimide is produced by heating the precursor to a suitable temperature over an appropriate period.
