METHOD FOR MANUFACTURING GLYCOL-MODIFIED POLY ETHYLENE TEREPHTHALATE COPOLYMERS AND APPLICATIONS THEREOF

摘要

The present invention describes a manufacturing method for a glycol-modified polyethylene terephthalate and an application for which. The manufacturing method includes the following steps. A reaction mixture is provided. The reaction mixture includes terephthalic acid, ethylene glycol, 1,4-cyclohexanedimethanol and an aqueous titanium-based catalyst. An esterification reaction and a polycondensation reaction is performed to the reaction mixture to obtain the glycol-modified polyethylene terephthalate.
