| titleOfInvention | Production of polyimide having good thermal stability |
| abstract | PURPOSE: To provide the subject polymer having good thermal stability and excellent moldability as well as the original excellent characteristics by condensing bis[(aminophenoxy)benzoyl]benzene with a tetracarboxylic acid dianhydride under a specified condition. n CONSTITUTION: An aromatic diamine comprising 1,4- and/or 1,3-bis[4-(3- aminophenoxy)benzoyl]benzene of formula I is condensed with a tetracarboxylic acid dianhydride (e.g. pyromellitic acid dianhydride) of formula II (R is a tetravalent group selected from ≥2C aliphatic groups, monocyclic aromatic groups, etc.) in a ratio of 0.9-1mol of the compound of formula I per mol of the compound of formula II in the presence of an aromatic monoamine (e.g. aniline) of formula: Z-NH 2 (Z is a monovalent group selected from monocyclic aromatic groups, condensed polycyclic aromatic groups, etc.) in an amount of 0.001-1mol per mol of the compound of formula II to provide the objective polymer having units of formula III as the basic skeleton thereof. n COPYRIGHT: (C)1990,JPO&Japio |
