Abstract

PURPOSE: A specific amount of phosphorus compound are incorporated to a composition consisting of an aromatic polyester, flat glass flakes, and an epoxy compound to produce title composition giving molded products free from warpage and good in thermal and mechanical characteristics.
CONSTITUTION: To a composition prepared by adding (B) 5 W 150, preferably 20 W 100 parts by wt of long platy glass flakes that has an aspect ratio over 5 and a long diameter less than 1000 microns after mixed, (C) 0.01 W 10 parts, per 100 parts of the total component A and component B, of an epoxy compound having 2 epoxy groups to (A) 100 parts by wt of an aromatic polyester of over 0.70 reduced viscosity, is incorporated (D) a phosphorus compound as phosphoric acid, esters or phosphonic acid derivative in such an amount that satisfies equations I and II. The addition of a rubber copolymer containing vinyl monomers further improves the impact characteristics.
