摘要：
This invention relates to polyester compositions that possess improved gas barrier properties. The novel copolyester blends comprise repeat units of phenylenedi(oxyacetic acid). Such copolyesters with improved gas barrier properties are useful in packaging applications where low gas permeability are required for protection or preservation of the contents.
