ABSTRACT Novel poly(aryl ether/thioether)-polyester block copolymers are prepared by reacting a polyester with a poly(aryl ether/thioether) having at least one electron-withdrawing group located in a position ortho or para to its ether/thioether linking group, in the presence of an exchange catalyst. The copolymers of the present invention exhibit high temperature stability and excellent thermoplastic engineering properties, as well as superior solvent resistance, making them particularly suited for producing molded plastic components for the automotive and eletrical housings markets. 37,080-F
