The mechanical anisotropy of injection moulded plaques of a liquid crystalline polymer based on a copolyester of p-hydroxybenzoic acid, isophthalic acid and hydroquinone has been studied. The inhomogeneity of the elastic anisotropy has been determined by a combination of static and ultrasonic measurements. The elastic constants are discussed in the light of previous results for anisotropic polymers and are shown to be consistent with an aggregate model to describe the relationship between mechanical anisotropy and molecular orientation.
