Unidirectional sheets were extruded of an in ‐ situ composite of thermotropic liquid crystalline Vectra B950 in a matrix of polyphenylene‐ether and polystyrene. Three important processing parameters were systematically varied: draw‐ratio, slit opening and extruder throughput. Morphology and mechanical properties of these films were determined, and qualitatively related to the processing conditions.
