ABSTRACT:
A poly(arylene ether ketone) of this invention principally comprises recurring units represented by formula ##STR1## wherein Ar.sup.1 denotes a 1,5-naphthalene ring, a 2,6-naphthalene ring, a 2,7-naphthalene ring or a combination of them, and Ar.sup.2 denotes p-phenylene, p,p'-biphenylene, a 1,5-naphthalene ring, a 2,6-naphthalene ring, a 2,7-naphthalene ring or a combination of them.
The poly(arylene ether ketone) is high in second-order transition temperature and excellent in solvent resistance and moldability, and can be molded into heat-resistant fibers and electric insulating films.
