Patent ID: 7816014

Claim:
A liquid crystalline polyester consisting essentially of a repeating unit represented by formula (A 3 ), as shown below: at least one repeating unit selected from units represented by formula (B 1 ) and (B 3 ) respectively, as shown below: and a repeating unit represented by formula (C 1 ), as shown below: wherein the amount of repeating unit (A 3 ) is from about 45 to about 65 mol%, the total amount of repeating units (B 1 ) and (B 3 ) is from about 27.5 to about 17.5 mol%, and the amount of repeating unit (C 1 ) is from about 27.5 to about 17.5 mol%, each based on the total molar amount of (A 3 ), (B 1 ) (B 3 ), and (C 1 ), and wherein the ratio of the total amount of repeating unit (B 1 ) and (B 3 ) to the amount of repeating unit (C 1 ) is about 1.
