Abstract
PURPOSE:To obtain a copolyimide fiber, containing phenylenediamine and biphenyltetracarboxylic acid dianhydride in a specific proportion, having excellent heat resistance, flame retardance and high-temperature dimensional stability and practical mechanical characteristics. CONSTITUTION:The aimed copolyimide fiber, containing a diamine component consisting of (A) (i) p-phenylenediamine and (ii) m-phenylenediamine and acid anhydride component consisting of (B) 3,3',4,4'-biphenyltetracarboxylic acid dianhydride and suitable as electrical insulating material, flameproof clothing, filters, vehicular inner trim materials, etc. The ratio of the component (i) in the above-mentioned diamine component is 30-80mol.%.
