Abstract

Bis-(beta-hydroxyethy)terephathalate oligomers are produced continuously by charging terephthalic acid and ethylene glycol, pref. in 1:1.6 molar ratio, to a stirred still, which operates continuously, where reaction to ca. 90% conversion takes place at normal pressure and pref. 230 degrees C; then charging to a flow tube reactor, in which conversion is completed at normal pressure and a temp. rising along the tube from pref. 240-270 degrees C, the av. degree of polycondens. attained being Pn =2. Alternatively, dimethyl terephthalate can be used instead of terephthalic acid, in which case the temp. in the tube reactor is 170-270 degrees C.
