Abstract

A novel composition comprising 100 parts by weight of an aromatic polyester, 5 to 150 parts by weight of powdery feldspar and optionally 5 to 120 parts by weight of a plate-like inorganic filler such as glass flakes and/or 1 to 100 parts by weight of a rubbery elastomer such as acrylic rubber. Up to a half of the powdery feldspar may be replaced by another pulverulent inorganic filler such as talc. The composition is useful as engineering plastics because it gives molded articles having high impact strength and heat distortion temperatures and reduced warping.
