Abstract

PURPOSE: To obtain title cpd. having good heat resistance and electrical characteristics and suitable for the production of electrical insulating materials, by a method wherein a diamino carbonamide is reacted with a diamine and a tetracarboxylic acid dianhydride in a specified weight ratio in an inert solvent.
CONSTITUTION: (a) A diamino carbonamide, such as 4,4'-diaminodiphenyl ether-3- carbonamide or 1,4-diaminobenzene-2-carbonamide, is reacted with (b) a diamine such as 4,4'-diaminodiphenyl ether, and (c) a tetracarboxylic acid dianhydride such as pyromellitic acid dianhydride in an amount of 5W20mol% of (a) based on the combined amount of (a) and (b), and pref. in an equimolar amount of (c) to the combined amount of (a)+(b) in order to obtain a polyamidic acid which is then heated to a temp. of not lower than 200°C to obtain a polyimide copolymer.
