A thermotropic liquid crystalline aromatic copolyester containing naphthalene rings (LCP) was blended with polysulfone and extruded. Rheological measurement shows that this LCP decreases blend viscosity to such an extent that the viscosity of blends even lower than that of LCP itself . In blend extrudates
an anisotropic and skin-core structure reinforced by LCP fibrils has been formed by shear flow of extrusion. Copolyester fibrils have been generated in extrudates even at LCP concentrations as low as 2 or 0.5%. LCP fibrils has increased tensile properties if oiktsykfibe
