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 compressing while heating for a short time. The thermoplastic polyimide has a tetracarboxylic dianhydride residue and a diamine residue, wherein a biphenyltetracarboxylic dianhydride residue comprises 80 mol% or more of the total amount of the tetracarboxylic dianhydride residue, a 4,4'-diaminodiphenyl ether residue comprises 65 to 85 mol% inclusive of the total amount of the diamine residue, and a para-phenylenediamine residue comprises 15 to 35 mol% inclusive of the total amount of the diamine residue.;COPYRIGHT KIPO & WIPO 2010
