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 multi layered, 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.

Abstract: Disclosed are oxygen-scavenging polymer compositions having high transparency and low haze comprising immiscible blends of one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, a copolyamide or a transamidized, homogeneous blend of a least two polyamides, and a metal catalyst. The components of the immiscible blend which 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 the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.

Abstract: The present invention concerns a method for forming an article by combining a polyester polymer and an oxygen scavenging composition comprising a polyamide in the presence of zinc and a cobalt in a melt processing zone to form a melt; and forming an article such as a sheet or preform from the melt. Also provided are molten formulated polyester polymer compositions containing a blend of a polyethylene terephthalate polymer and a polyamide polymer along with zinc and cobalt. Articles made from the composition are resistant to the transmission of oxygen, possess short induction periods, and have high capacity for sustaining lengthy periods of low oxygen transmission through the wall of the article.

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.
