Abstract:
Thermotropic liquid-crystalline aromatic polyesters processable in the molten state, comprising units derived from at least one dicarboxylic aromatic acid and from mono- and di-substituted (1-phenyl-ethyl)-hydroquinones in admixture with hydroquinone, and/or hydroquinones substituted with halogen or alky, aryl or cycloalkyl groups.
