Disclosed is a process for the preparation of multilayered, shaped
articles having high transparency and low haze and in which at least one
layer contains at least one polyester comprising
2,2,4,4-tetramethyl-1,3-cyclobutanediol and a separate layer which
contains a transamidized, homogeneous blend of a least two polyamides.
The polyester component and the polyamide component 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.
