ABSTRACT:
Block copolymers represented by the formula ##STR1## are formed by contacting an ester group containing poly(aryl ether ketone) composed of the recurring units ##STR2## with a liquid crystalline polyester represented by the formula ##STR3## in which R.sub.1, R.sub.2 X.sub.2, X, Z, E.sup.1, E.sup.2 E.sup.5, w, x, y, z a, b and n each represent specified groups or values under conditions such that a transesterification reaction will occur.
