    Abstract: Oxygen-scavenging polyester compositions are disclosed that include residues of one or more unsaturated diols, for example, 2-butene-l,4-diol, and residues of one or more aliphatic dicarboxylic acids, for example adipic acid. The compositions may be used as concentrates, and may be blended, for example, with one or more polyethylene terephthalate homopolymers or copolymers, to obtain compositions suitable for use in packaging, providing oxygen-scavenging effect.

    Abstract: Oxygen-scavenging polyester compositions are disclosed that comprise one or more polyesters having incorporated therein residues of 3-hexenedioic acid and terephthalic acid. The compositions may further comprise residues of one or more aliphatic dicarboxylic acids such as adipic acid. One or more of the polyesters of the compositions may comprise significant amounts of repeating units of polyethylene terephthalate as homopolymers or copolymers, making them suitable for us in packaging compositions having oxygen-scavenging properties.

    Abstract: Polymer blends suitable for packaging are disclosed that include a transition metal; one or more polyamide homopolymers or copolymers; and one or more polyethylene terephthalate homopolymers or copolymers obtained by a melt phase polymerization using a catalyst system comprising aluminum atoms in an amount, for example, from about 3 ppm to about 60 ppm and one or more alkaline earth metal atoms, alkali metal atoms, or alkali compound residues in an amount, for example, from about 1 ppm to about 25 ppm, in each case based on the weight of the one or more polyethylene terephthalate homopolymers or copolymers. The polymer blends disclosed exhibit improved oxygen-scavenging activity compared with blends made using polymers prepared with conventional catalyst systems.

    Abstract: Disclosed is a process for the preparation of multilayered, shaped articles having high transparency and low haze having at least one layer contains one or more thermoplastic polymers selected from polyesters, polycarbonates, and homogeneous blends thereof, and a separate layer which contains 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.
