Abstract: The invention relates to improved resin bonded sorbent compositions and articles of manufacture fabricated therewith, such as housings, structural components and circuit boards. The introduction of sorbents into resinous molding compositions enables the elimination of more conventional bagged sorbent containments. The novel molding compositions of the invention and parts fabricated therewith are multi-functional, beneficially combining structural, mechanical and adsorptive capabilities without requiring the usual reinforcing additives. Consequently, with the omission of reinforcing additives the novel molding compositions of the invention are further characterized by higher adsorptive capacities by allowing for higher sorbent loading factors than prior adsorbent-containing molding compositions.

Abstract: Heterogeneous oxygen-scavenging particles are formed by dry coating activating component particles onto oxidizable component particles, largely through a succession of mechanical motions. The component particles are repeatedly mixed, compressed, and sheared. Smaller activating component particles coat the surface of larger oxidizing component particles by force-induced contact, while irregularities are removed by abrasion among the particles. The oxygen-scavenging particles can be blended together with a base polymer into a masterbatch having a higher concentration than required for use as an active barrier to oxygen permeation. The masterbatch can be diluted with the same or a compatible polymer to form the active barrier.
