Abstract

PURPOSE: To produce a polyamide block copolymer and the like excellent in quality and processability under a relatively mild condition, by reacting an isocyanato group-terminated polyamide or the like with a carboxyl group (or anhydrido group)-terminated polyamide or the like.
CONSTITUTION: A block copolymer is produced by reacting at least one isocyanate group-terminated compound selected from the group consisting of a polyamido, a polyamide-imide and a polyimide, represented by formulasI, II and III, respectively, wherein R1 is a bivalent 2C or higher group, R2 is a bivalent 2C or higher group, R3 is a trivalent 3C or higher group and R4 is a tetravalent 4C or higher group, with at least one carboxyl group and/or anhydrido group- terminated compound selected from the group consisting of a polyamide, a polyamide-imide and a polyimide, represented by formulas IV, V and VI, respectively, at about 20W250°C for about 1W 20hr in an anhydrous organic polar solvent while removing the by-product, CO2, under a stream of an inert gas.
