Abstract

PURPOSE: A polyester (molded product) which keeps its inherent properties and is excellent in dyeability and light resistance, prepared from an alkylene glycol component and a dicarboxylic acid component having a specified composition.
CONSTITUTION: Titled modified polyester is prepared by charging a dicarboxylic acid component consisting of not less than 80mol% terephthalic acid (derivative), 0.5W5mol% 5-metal-sulfoisophthalic acid, e.g., dimethyl 5-sodiosulfoisophthalate (derivative) and 0.5W5mol% dimer acid (derivative) and about 1.1W4mol times alkylene glycol component, transesterifying the mixture at about 150W230°C in the presence of a catalyst, e.g., zinc acetate, and then, polycondensing the mixture at about 230W280°C.
