WHOLLY AROMATIC POLYESTER, COMPOSITION THEREOF, AND MOLDED ARTICLE MADE THEREFROM.

摘要

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 ovenware 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 fluororesin without the necessity for pretreatment such as heat treatment.
