CONTINUOUS PREPARATION FOR POLYESTER

摘要

The present invention relates to a method for continuous polymerization of polyester and, more specifically, to a method for continuous polymerization of polyester and to a polymerization reactor applied thereto, the method comprising: obtaining an ester oligomer by performing esterification or trans-esterification; and continuously injecting the ester oligomer in a liquid polymerization reactor to continuously produce polyester polymers in the liquid polymerization reactor.
