Abstract: A thermoplastic composition that comprises a low-naphthenic, thermotropic liquid crystalline polymer blended with a flow modifier is provided. The flow modifier is an aromatic carboxylic acid that contains one or more carboxyl functional groups.

As a result of the present invention, the melt viscosity of the thermoplastic composition is generally low enough so that it can readily flow into the cavity of a mold having small dimensions.
