Abstract
Polyetheramide acids and polyetherimides derived therefrom are provided having terminal aliphatically unsaturated groups. The polyetherimides are heat curable, have superior flow characteristics prior to cure, and can be converted to high strength shaped composites when reinforced with various materials such as carbon fibers, glass fibers, etc.
