| titleOfInvention | Heat-resistant resin composition |
| abstract | PURPOSE:To obtain the title composition having excellent solubility in a solvent and heat resistance, by dissolving a specified polyamide-imide resin in an organic solvent and dissolving an N,N'-bismaleimide and a diamine-terminated amic acid in this solution. CONSTITUTION:A polyamide-imide resin (A) of formula I (wherein R<1> is a 6-20C trivalent aromatic group; R<2> is a 6-20C divalent aromatic group), prepared from a diamine and an acid chloride of a tribasic acid anhydride is dissolved in an organic solvent to give a solution. An N,N'-bismaleimide (B) of formula II (wherein R<3> is a 2-20C divalent organic group) (e.g., N,N'-4,4'- diphenylmethanebismaleimide) is mixed with a diamine-terminated amic acid (C) of formula III (wherein R<4> is R<3> and R<5> is a 6-20C tetravalent aromatic group) obtained by addition reaction of a tetracarboxylic acid dianhydride with a diamine, the molar ratio of component B to component C being 1-3:1. This mixture is dissolved in the above-mentioned solution so as to provide a weight ratio, on a solid basis, of A to B + C of 0.5-10. |
