Abstract
A wholly aromatic polyester having excellent moldability, heat resistance and blistering resistance and a composition thereof are obtained from an aromatic polyester composed of six specified types of structural unit and having an optical melt anisotropy. The composition can provide electronic heater parts and oven-ware both excellent in mechanical strength, heat resistance, moldability and microwave oven resistance, and various other heat-resistant members. Molded articles made from this composition can be coated with fluorocarbon resin without the necessity for pretreatment such as heat treatment.
