| titleOfInvention | Polyester resin and preparation method thereof |
| abstract | The present invention provides a polyester resin, which includes: a unit containing a terephthalic acid dicarboxylic acid component; and a unit containing a diol component containing isosorbide, cyclohexanedimethanol, and other diol compounds. The polyester resin includes a zinc-based catalyst and a phosphorus-based stabilizer. The polyester resin has an intrinsic viscosity within a specific range, and the oxygen permeability is less than 20 ml * mm / (square meter * day * atmospheric pressure), measured according to ASTM D 3985. The present invention also provides a method for preparing a polyester resin. In the presence of a zinc compound-containing esterification catalyst, esterification includes a diol component containing isosorbide, cyclohexanedimethanol, and other diol compounds, and a p-benzene-containing compound. The dicarboxylic acid component of dicarboxylic acid; when the degree of esterification reaches at least 80%, add a phosphorus stabilizer to the esterification reaction mixture; and polycondensate the product of this esterification reaction. |
