Liquid crystalline polyesters

摘要

The present invention provides a novel liquid crystalline polyester comprising structural units represented by the following general formulae A, B, C and D: <IMAGE> <IMAGE> <IMAGE> <IMAGE> where X and Y are each independently H, Cl, Br or an alkyl group having 1 to 4 carbon atoms, the molar ratio of A/B is in the range from 49/1 to 20/30 and that of C/D is in the range from 10/40 to 45/5.
