Abstract: Disclosed is a process for a melt processing a polyethylene terephthalate. The polyester particles have at least two melting peaks. The polyester particles may have an It. V. at their surface which is less than 0.25 dL/g higher than the It. V. at their center. The polyester particles may have not been solid stated. The melt processing device comprises a screw with a total length (9), L, a feed zone length (3) in the range from 0.1 SL and 0.45L, a taper angle, in the range from 0.5 degrees and 5.0 degrees and a compression ratio, CR, in the range from 2.0 and 5.0.

Abstract: Disclosed is a process for the preparation of multilayered, shaped articles having high transparency and low haze and comprising one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The thermoplastic polymer components and the polyamide components have refractive indices which differ by about 0.006 to about -0.0006. The small difference in the refractive indices enable the incorporation of regrind into one or more of the layers of the article while maintaining high clarity. These articles can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into one or more layers to impart oxygen-scavenging properties.
