Abstract
A melt-processable composition comprising at least one polymer capable of forming an anisotropic melt and at least one other melt-processable polymer characterized in that the temperature range over which the polymer can form an anisotropic melt overlaps the temperature range over which the melt-processable polymer may be melt processed. The melt viscosity of such compositions may be very much less than that of the melt-processable polymer in the absence of the anisotropic melt-forming polymer particularly at high shear rates, corresponding to those encountered during moulding and extrusion operations.
