Abstract
A cured or uncured linear aromatic polyester composition melt-blended and composed of PA1 (A) 100 parts by weight of a saturated linear aromatic polyester in which at least 70 mole % of the acid component consists of an aromatic dicarboxylic acid, and PA1 (B) 0.1 to 50 parts by weight of a reactive compound which is solid at room temperature or is a liquid having a boiling point of at least 200.degree. C. under atmospheric pressure, and which contains in its molecule at least one aliphatic unsaturated group substantially non-reactive with the polyester (A) and the aliphatic unsaturated group of the reactive compound (B) under conditions of melt-blending with the polyester (A) and at least one epoxy group reactive with the polyester (A) under the melt-blending conditions. The cured linear aromatic polyester composition can be prepared by extruding the uncured linear aromatic polyester composition under melting conditions, and subjecting the resulting extrudate to a curing treatment.
