Abstract

PURPOSE: To produce a high-polymer material which is soluble in a solvent and has high molecular weight, by a method wherein a polyamide is melt-kneaded together with a copolymer contg. an α,β-unsaturated carboxylic acid anhydride.
CONSTITUTION: 70W99wt% Polyamide (A) having 0.5W1.5 terminal amino groups per molecule (e.g. nylon 6) and 30W1wt% copolymer (B) (having a number- average MW of 10,000 or higher and consisting of 2W15wt% α,β-unsaturated carboxylic acid anhydride and 98W85wt% styrene), are kneaded together at a temperature not lower than the melting temp. of component A to produce a high- molecular material having a solution viscosity of 1.0dl/g or higher when a solution having 0.5% polymer concentration in a 9:1 mixed solvent of m-cresol and methyl ethyl ketone is measured at 30°C.
EFFECT: There can be obtd. molded articles having excellent mechanical performance, wear resistance, etc.
