    摘要: The invention relates to blends of polyamides in polyesters, a method for forming such compositions, and to containers made from such compositions. Specifically the compositions have less haze and transparency than previous blends. The blends can be used as passive gas barriers, and/or active oxygen scavengers with the addition of a transition metal catalyst. The invention seeks to obtain balanced refractive indices for the polyamides/polyester compositions. A method to blend the copolyester and polyamides and orient the blend to minimize the haze, thereby forming an oriented article, is also described and claimed. These articles have excellent gas barrier properties.
