SHAPED ARTICLES FORMED FROM POLYMERS CAPABLE OF EXHIBITING ANISOTROPIC MELTS

摘要

Shaped articles are provided containing a polymer which is capable of exhibiting anisotropy in the melt and an inert filler characterised in that the inert filler is selected from a) sufficient of a fibrous filler to reduce the anisotropy ratio in the article at least to that obtained from an otherwise similar composition in which the polymer capable of exhibiting anisotropy in the melt is replaced by an isotropic melt forming polymer b) sufficient of a particulate filler to reduce the anisotropy ratio by at least 50% c) at least 10% by volume of voids wherein the anisotropy ratio is the ratio of the stiffness in two directions at right angles in the shaped article.
