| titleOfInvention | Polyimide and heat-resistant adhesive comprising same |
| abstract | PURPOSE:To obtain a polyimide having excellent processability as well as excellent heat resistance inherent in polyimide, having a low water absorptivity and good transparency and being useful as a heat-resistant adhesive, comprising a specified ether diamine and a tetracarboxylic acid dianhydride. CONSTITUTION:This polyimide has repeating units of formula I (wherein R is a tetravalent group selected from among a 2C or higher aliphatic group, a cycloaliphatic group, a monocyclic aromatic group, a condensed polycyclic aromatic group and an noncondensed polycyclic aromatic group and a noncondensed polycyclic aromatic group composed of aromatic groups bonded together directly or through bridging members). Said polyimide can be obtained by effecting ring closure through dehydration of a polyamic acid obtained by polymerizing an ether diamine of formula II, namely, bis[4-{4-(4-aminophenoxy) phenoxy}phenyl]sulfone with at least one tetracarboxylic acid dianhydride. |
