Abstract

The provided are a polylactic acid-polyalkylene glycol copolymer and a composition comprising the same which have excellent crystallization rate, wherein the polylactic acid-polyalkylene glycol copolymer is prepared by melt-reacting polylactic acid with polyalkylene glycol of which one end group is substituted with a functional group and has improved eco-friendliness, injection moldability, and excellent heat resistance which makes it to be suitably applied to various molded articles requiring great heat resistance, such as disposables, kitchen utensils and containers, electric-electronic parts and automobile parts.
