MANUFACTURING METHOD OF A POLYLACTIDE RESIN WITH LOW ACIDITY AND HIGH MOLECULAR WEIGHT AND A POLYLACTIDE RESIN MANUFACTURED BY THE SAME

摘要

PURPOSE: A manufacturing method of a polylactide resin is provided to manufacture a polylactide resin of low acidity and high molecular weight in high yield.;CONSTITUTION: A manufacturing method of a polylactide resin comprises a step of ring-opening polymerizing a cyclic ester compound under the presence of a compound represented by chemical formula 1. In chemical formula 1, R^1, R^2, R^3, and R^4 are the same or different from each other and each is hydrogen, a hydroxy group or amine group-substituted or unsubstituted C1-10 linear or branched alkyl, a hydroxy group or amine group-substituted or unsubstituted C2-10 linear or branched alkenyl group, or a hydroxy group or amine group-substituted or unsubstituted C2-10 linear or branched alkynyl.;COPYRIGHT KIPO 2013
