A polymer composition includes a low ethylene random copolymer that can be used to form a meltspun or spunbond article at high spinning velocities. The polymer composition has a low xylene soluble content, a high crystallinity, or both, while having reduced spin-break at high spinning velocities. The polymer composition also exhibits good fiber tenacity and fabric softness.

An oxygen absorbing resin composition containing a polyolefin, an iron powder, titanium oxide, and calcium oxide, a content of the iron powder being from 10 to 50 mass % in the oxygen absorbing resin composition, a mass ratio of the titanium oxide to the iron powder [titanium oxide/iron powder] being from 0.1 to 0.5, and a mass ratio of the calcium oxide to the iron powder [calcium oxide/iron powder] being from 0.1 to 0.5.

The present invention provides a reaction mixture comprising a polyuretdione resin, a neutralized polyol, an acid-blocked tertiary amine catalyst, and optionally, an additive package selected from the group consisting of flow control additives, and wetting agents, and solvents, wherein the acid has a pK.sub.a of greater than 4.82. Compositions made from the reaction mixture of the present invention may be catalyzed at temperatures from room temperature to 130 C. and are particularly applicable in or as coatings, adhesives, castings, composites, and sealants with good performance and extended pot-life.

An oxygen scavenging formulation comprising an oxidizable polymer resin, a transition metal catalyst, and a photosensitizer selected from one or more carotenoids is provided. The oxygen scavenging formulation does not need an additional triggering agent, or heating or light irradiation to trigger an oxygen scavenging function. A method of reducing oxygen atmosphere in a packaging article is also provided.

Described herein are oxygen scavengers, oxygen scavenging polymeric compositions, and oxygen scavenging articles. The polymeric compositions comprising the oxygen scavengers may have utility in packaging, sealing, wrapping, and storing oxygen-sensitive substances, e.g., to preserve freshness of foods, beverages, and the like.

A fibrous insulation product is provided comprising a nonwoven fiber mat including a plurality of fibers bound together by an aqueous binder composition comprising that includes a thermally degradable polyol; a crosslinking agent; and an acid/aldehyde. The binder composition is free of added formaldehyde.

Disclosed herein is an oxygen scavenging composition for containers. The oxygen scavenging composition may comprise at least one polyester component, which is a copolyester containing a metal sulfonate salt group, a transition metal catalyst, and a vegetable oil. The vegetable oil may comprise at least one molecule having a double allylic structure. The copolyester containing a metal sulfonate salt group may comprise at least one acid unit and at least one diol unit. The concentration of the 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 composition may also be void of or substantially void of a polyamide.

The present invention provides a method for reducing a drawing force in a forming process of a photocurable material by adding a radical scavenger capable of terminating free radical polymerization into a substrate for carrying the photocurable material. The method comprises: providing a mold release composition at least comprising a radical scavenger and a molding agent; and forming a mold release film from the mold release composition by curing forming or by combining with an upper surface of a plate, thereby preparing the substrate. In this way, during the light curing reaction of the photocurable material by irradiation with a light source, the radical scavenger in the upper surface of the substrate contacting with the photocurable material can re act with free radicals in the photocurable material, such that the photocurable material forms an uncured layer for which light curing does not occur on the upper surface of the substrate.

Disclosed herein is a preform having a preform wall. The preform wall preferably comprises a composition comprising at least one polyester component, a transition metal catalyst, and a vegetable oil. The vegetable oil may comprise at least one molecule having a double allylic structure. The at least one polyester component may comprise 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 preform has improved aesthetic characteristics.
