Abstract
A polylactic acid resin and a method for preparing same, the polylactic acid resin having the feature that the melt index of the polylactic acid resin can be increased and the flowability can be improved through a simple method of treating the polylactic acid resin with water. The method also makes it possible to improve the reactivity of the polylactic acid resin and improves its compatibility with various additives, thereby expanding the application fields of the polylactic acid resin.
