ABSTRACT:
Polyamide-hydrogenated polybutadiene-acrylonitrile block copolymers having high solubility in organic solvents, good compatibility with other polymers, and excellent thermal resistance and adhesive properties are characterized by comprising block units (A) represented by the following formula (I) and block units (B) represented by the following formula (III): ##STR1## wherein Bu is hydrogenated butadiene radical, R is divalent organic radical, R' is a divalent aromatic group having a hydroxyl group, Ar is an aromatic divalent group represented by the following formulae (1)-(6): ##STR2## each of k and z is an average polymerization degree where k is an integer of 2-400, and z is an integer of 5-100, m and n are molar fractions in the copolycondensation, where m.gtoreq.0.04, and m+n=1, and x and y are molar fractions in the copolymerization, where x:y=0.95:0.05 to 0.6:0.4, and x+y=1, and block units (A) and (B) are contained in the range of 2 to 20, respectively.
