A thermoplastic polymer composition comprising a thermotropic polymer and 0.025 to 5% by weight of the composition of a finely dispersed particulate inorganic additive wherein the additive is a material having at least 95% by weight of particles with at least one dimension less than 1 micron and preferably less than 0.1 micron and is an organophilic or organophobic material which has a settling volume of at least 10 when measured in a liquid in which the particulate material is compatible. The presence of the inorganic additive in the thermotropic polymer gives rise to an improved processing behavior.
