Oxygen scavenging polyester compositions for containers
Disclosed herein is an oxygen scavenging composition for containers. The oxygen scavenging composition for containers may comprise at least one polyester component, a transition metal catalyst, an oxygen scavenger, and a vegetable oil. The vegetable oil preferably comprises at least one molecule having a double allylic structure. The polyester component preferably comprises at least one acid unit and at least one diol unit. The concentration of double allylic structures of the vegetable oil in the composition may be greater than 5.0 meq/kg of all of the polyester components. The oxygen scavenger is preferably present in the composition at a level less than 1.0% by weight of the total composition. The vegetable oil is preferably present in the composition at a level greater than 0.3% by weight relative to the total weight of the polyester components, the transition metal catalyst and the vegetable oil.
Thermal amplification of free radical polymerization induced by red to near-infrared irradiation
The present invention relates to compositions thermally curable on demand by red to near infrared irradiation, method of using same for thermal amplification of free radical polymerizations, and articles obtained by such method. The invention also relates to the use of a heat-generating dye in association with a thermal initiator for controlling the onset of thermal free radical polymerization.

Compositions using polyuretdione resins
The present invention provides a reaction mixture comprising a hot blend of a first isocyanate-based uretdione resin and a second isocyanate-based uretdione resin, a neutralized polyol and a tertiary amine catalyst, and optionally, an additive package selected from the group consisting of flow control additives, pigments (colorants), wetting agents, and solvents, wherein the first isocyanate and the second isocyanate are different. The isocyanate-based uretdiones that have been hot blended together produce coatings, adhesives, castings, composites, and sealants, which exhibit better performance properties (such as microhardness) than those coatings, adhesives, castings, composites, and sealants produced from the constituent isocyanate-based uretdiones alone.
