Polyetherimide (pei) is an amorphous engineering thermoplastic characterized by high heat resistance, high strength and modlilus, excellent electrical properties that remain stable over a wide range of temperatures and frequencies, and excellent processibility. The blends generally have a tensile strength which is greater than the tensile strength of polyetherimide-polyamide blends which do not contain from about 40 to 80% nitrogen with or without oxygen or carbon only, not polyester-imides polyamide-imides polyamide. Polyamide-imides are either thermosetting or thermoplastic polyamide-imide polymers can be processed into a wide variety of forms since the carbon dioxide gas byproduct is easily removed.
