Abstract

PURPOSE: Bis-β-hydroxyethylterephthalate and its oligomer are prepared by introducing the slurry of terephthalic acid and ethyleneglycol continuously into the reaction system containing the reaction products, and esterfying the reactants by distilling out a particular amount of water with glycol from the system.
