Polymers prepared from 4,4'-bis[2-(amino (halo) phenoxyphenyl) hexafluoroisopropyl]diphenyl ether

摘要

This invention relates to new 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 invention are characterized by the fact that they are derived from 4,4'-bis[2-(amino(halo)phenoxyphenyl)hexafluoroisopropyl]diphenyl ether.
