    Abstract: A liquid crystalline polymer contains (A) 100 parts by weight of a liquid crystalline polyester and/or liquid crystal polyesteramide capable of forming an anisotropic melt and (B) 0.01 to 2 parts of an olefinic polymer. The composition is especially suitable for moulding therefrom shaped articles by a moulding process in which at least two flowing molten resin portions of the composition unite to form a weld. Thus, using such a composition it is possible to produce a moulding having such a weld in which the weld has a weld strength retention of 15% to 100%, so that the shaped article has excellent heat stability, mechanical properties, dimensional stability and mold releasability and is suitable for various application uses such as in electrical and electronic devices, accurate machine devices, office related devices and automobile parts.
