Title:
METHOD FOR PREPARING HIGH-VISCOSITY ISOSORBIDE POLYETHYLENE TEREPHTHALATE POLYMER
Document Type and Number:
WIPO Patent Application WO/2017/131372
Kind Code:
A1
Abstract:
The present invention provides a method for preparing a high-viscosity isosorbide polyethylene terephthalate polymer, comprising: a step of preparing a slurry by mixing ethylene glycol (EG), terephthalic acid (TPA) and isosorbide of the following chemical formula 1; an esterification step of the slurry; a melt polymerization step; and a solid state polymerization step, wherein the isosorbide is injected in an amount of 4.0-10 mol%, and more preferably, 4-6 mol% on the basis of TPA. The present invention can prepare a high-viscosity isosorbide polyethylene terephthalate polymer, which can be used in an industrial fiber, by adding isosorbide when preparing the polyethylene terephthalate polymer.
