Patent ID: 7985456

Claim:
A polymer blend having oxygen scavenging activity, comprising: one or more polybutadiene homopolymers or copolymers having at least one functionality capable of entering into condensation reactions; one or more polyethylene terephthalate homopolymers or copolymers obtained using a catalyst system comprising: aluminum atoms in an amount from about 3 ppm to about 100 ppm, and one or more alkaline earth metal atoms, alkali metal atoms, or alkali compound residues in an amount 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; and one or more transition metal atoms in an amount from about 10 ppm to about 1,000 ppm metal, based on the total weight of the polymer blend.
