| abstract | PURPOSE: To provide the titled compsn. for forming heat-resistant films, excellent in storage stability and containing a high concn. of resin, by incorporating a small amt. of melamine(derivatives) in a particular polyamide-imide resin terminated with alcohol and dissolving in solvents. n CONSTITUTION: Preferably in an org. solvent (e.g., N-methyl-2-phrrolidone), a polyfunctional isocyanate (e.g., diphenylmethane diisocyanate) and a tribasic acid anhydride(derivative) (e.g., trimellitic anhydride) are allowed to react to form a heat-resistant resin with reduced viscosity of 0.1W0.4. About 1W3wt% alcohol (e.g., methanol or butanol) is added to 100wt% said resin, and the mixture is allowed to react at a temp. above about 40°C for about 0.1W20hr to block the terminal isocyanate. Then, about 0.1W0.9pts.wt. melamin(derivative) (e.g., monomethylolmelamine) is added to 100pts.wt. above resin, and the mixture is diluted with a proper amt. of a solvent, yielding a heat-resistant resin compsn. n COPYRIGHT: (C)1985,JPO&Japio |
