Title:
PRODUCTION OF HEAT-RESISTANT RESIN
Document Type and Number:
Japanese Patent JPH01165624
Kind Code:
A
Abstract:
PURPOSE:To obtain a resin good in heat resistance, moisture resistance and adhesiveness and curable at low temperatures, by reacting a tetracarboxylic acid dianhydride component containing a specified tetracarboxylic acid dianhydride as an essential component with a diamine component containing a specified diamine as an essential component. CONSTITUTION:A polyimide resin comprising a tetracarboxylic acid dianhydride and a diamine is prepared by reacting a tetracarboxylic acid dianhydride component containing at least 20mol% diphenyl sulfone-3,3',4,4'-tetracarboxylic dianhydride with a diamine component containing at least 50mol% 2,2-bis[4-(4- aminophenoxy)phenyl]propane at 0-80 deg.C in an organic polar solvent.
