Abstract
PURPOSE: To obtain polytetramethylene terephthalate isophthalate copolymers having excellent properties with the decrease of by-products and a reaction time, by the esterification of terephthalic acid and isophthalic acid with tetramethylene glycol in the presence of novel effective catalysts and the following polycondensation.
