发明名称 WHOLLY AROMATIC LIQUID CRYSTALLINE POLYESTER AND METHOD OF PRODUCING THE SAME
摘要 A wholly aromatic liquid crystalline polyester contains 2.0 to 15.0 mole percent of a hydroquinone-derived structural unit relative to a total amount of structural units. The wholly aromatic liquid crystalline polyester has sum of an amount (a) of terminal hydroxyl group and an amount (b) of terminal acetyl group in a range of 50 to 350 equivalents/(g·10−6), and has a ratio [(a)+(b)]/(c) of the sum of the amount (a) of terminal hydroxyl group and the amount (b) of terminal acetyl group to an amount (c) of terminal carboxyl group in a range of 1.05 to 2.00.
