ALIPHATIC POLYESTER RESIN AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed are an aliphatic polyester resin having excellent moldability, and a method for producing such an aliphatic polyester resin. Specifically disclosed is an aliphatic polyester resin wherein the amount of a specific constitutional unit contained in the aliphatic polyester resin is controlled to an optimum amount. This aliphatic polyester resin has sufficient melt tension during molding, and thus attains more excellent moldability than the conventional ones. Also specifically disclosed is a method for producing such an aliphatic polyester resin.
