Abstract
Blends of polyester-carbonates and/or polyarylate resins with polyetherimide resins are thermoplastically molded to obtain ductile, high distortion temperature articles. The polyester-carbonate resin or polyarylate resin is selected from a particular class prepared by polymerization of a dihydric phenol, and an ester precursor which is terephthalic acid, optionally with a proportion of isophthalic acid.
