Abstract: This invention relates to aliphatic-aromatic copolyesters that can exhibit improved tear strength and improved rate of biodegradation. Particularly to an aliphatic-aromatic copolyester having a dicarboxylic acid component and a glycol component. The invention also relates to articles and blends using the copolyesters.

Abstract: The polymerization processes described herein provide methods for dehydrating diols such that dimers of the diols are formed and incorporated into polyesters during polycondensation. Control over this phenomenon provides unique polymer compositions with a range of thermo-mechanical properties, crystallinity, bio-content and biodegradability. Generation of a wide range of properties allows development of polymers that can be used for a wide range of applications.

Abstract: A coating composition having an multicopper oxidase enzyme and an oxidizable substrate in combination with an organic binder polymer which may be dispersed or dissolved in a non-aqueous liquid vehicle.

Abstract: The invention is directed to a method for preparing an oxygen scavenging film and package by inclusion of an oxygen scavenging coating that is activable upon exposure to water vapor during final package assembly. The film includes a composition having a non-aqueous liquid vehicle, a multicopper oxidase enzyme, an oxidizable substrate and an organic binder polymer, wherein the polymer is dissolved or dispersed in the liquid vehicle, wherein the enzyme and the substrate are in particulate form and dispersed in the liquid vehicle; and wherein the liquid vehicle is evaporated.

Abstract: The composition of the present invention, combining multicopper oxidase enzyme, oxidizable substrate, and iron, exhibits a rate of oxygen scavenging that is in excess of that predicted from the rule of mixtures applied to the combination of enzyme/substrate and iron/substrate compositions that are known in the art.
