POLY(GLYCOLIC ACID)-BASED RESIN COMPOSITION AND FORMED ARTICLE THEREFROM

摘要

A poly(glycolic acid)-based resin composition which comprises a major amount of poly(glycolic acid) and a minor amount of an aromatic polyester resin. The composition exhibits improved stability to moisture and improved heat melting processability as compared to those of a poly(glycolic acid) resin, while retaining excellent characteristics of a poly(glycolic acid) resin representatively shown by gas-barrier properties. The composition also exhibits improved stretching properties, which in turn provides a formed article having improved transparency through stretching.
