THERMOPLASTIC POLYIMIDE, AND LAMINATED POLYIMIDE FILM AND METAL FOIL-LAMINATED POLYIMIDE FILM USING THE THERMOPLASTIC POLYIMIDE

摘要

Disclosed is a thermoplastic polyimide which has excellent heat resistance and can adhere to a metal foil by thermocompression bonding for a short-time. The thermoplastic polyimide comprising a tetracarboxylic dianhydride residue and a diamine residue wherein the biphenyl tetracarboxylic dianhydride residues account for 80 mol% or more of the total tetracarboxylic dianhydride residues, the 4,4'-diaminodiphenyl ether residues for 65 mol% or more and 85 mol% or less of the total diamine residues, and the paraphenylene diamine residues for 15 mol% or more and 35 mol% or less of the total diamine residues.
