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.
