摘要：Disclosed are oxygen-scavenging polymer compositions having high

transparency and low haze comprising immiscible blends of one or more thermoplasticpolymers selected from polyesters, polycarbonates, and polyarylates, a copolyamide ora transamidized, homogeneous blend of a least two polyamides, and a metal catalyst.The components of the immiscible blend which have refractive indices which differ byabout 0.006 to about −0.0006. The small difference in the refractive indices enable theincorporation of regrind into the polymer composition to produce transparent shapedarticles. The blends of the present invention are useful in producing shaped articles suchas, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles mayhave one or more layers and can exhibit improved excellent barrier properties and goodmelt processability while retaining excellent mechanical properties.
