Abstract
Novel copolyamides having the recurring unit ##STR1## are disclosed wherein Ar in the major proportion of the recurring units is m-phenylene and in the corresponding minor proportion (but more than 10 percent) of the recurring units Ar is a phenylene ether having the formula ##STR2## The copolyamides have excellent high temperature resistance but, unlike those polymers in which Ar in the above recurring unit is exclusively m-phenylene, they can be injection molded.
