Polymers prepared from 4,4'-bis-2-(3,4-(dicarboxyphenyl) hexafluoroisopropyl diphenyl ether dianhydride

摘要

The application relates to fluorine-containing polyimides, polyamide-acids/esters, polyamides, addition polyimides and imide oligomers which exhibit low melting points, better solubilities, low dielectric constants, superior thermal and thermal oxidative stability, and improved processing characteristics.;The products of this application are characterized by the fact that they are derived from 4,4'-bis[2-(3,4-(dicarboxyphenyl)­hexafluoroisopropyl]diphenyl ether dianhydride.
