Abstract: Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise solid particles comprising palladium in combination with at least one of antimony, bismuth and gold, and optionally, an additional metal or metalloid component effective to promote activity or selectivity of the palladium and antimony, bismuth or gold for oxidation to aromatic carboxylic acids. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such catalytic compositions in a liquid reaction mixture.

Abstract: A method for replenishing carbon dioxide gas in a carbonated beverage container where a carbon dioxide regulator releases carbon dioxide at a rate approximately equal to the rate of carbon dioxide loss from said container. Also disclosed is packaging system for maintaining a consistent pressure of a carbonated beverage comprising a closure, a plastic container, and a carbon dioxide regulator. Also disclosed is a method for making a packaging system for maintaining a consistent pressure in a carbonated beverage comprising overmolding a perform around an assembly for a carbon dioxide regulator, or blending a carbon dioxide regulator into the plastic material used to form the body of a container for said carbonated beverage. Also, disclosed is carbon dioxide regulator composition for replenishing carbon dioxide gas in a carbonated beverage container comprising polymeric carbonates, organic carbonates, or materials that absorb and subsequently release carbon dioxide.

Abstract: Improved active oxygen scavenging packaging articles optionally further comprising SiO2 and/or EAA coatings are disclosed. Also improved active oxygen scavenging copolycondensates and their use in packaging articles are disclosed. Specifically disclosed are (1) the use of an oxidation moderator or controller (anti-oxidant) along with the copolycondensate scavenger and (2) post polymerization treatment of the copolycondensate substantially in the absence of oxygen. The improvements lead to increased oxygen consumption by the active oxygen scavenger and improved packaging characteristics for the active oxygen scavenging copolycondensates.

Abstract: Hot-melt adhesives based upon a mixture composed of poly(vinylmethylether), greater than about 10 weight percent of a thermoplastic resin and, optionally a tackifier resin and/or extender, are found to be superior for the binding of polyolefins such as polyethylene, polypropylene, and ethylene-propylene copolymers to themselves and to other substrates. In particular, the hot-melt adhesives are useful for bonding polyethylene-backed and latex-backed carpet to polyethylene, polypropylene, or ethylene-propylene copolymer.

Abstract: A process is disclosed for the preparation of liquid and aqueous solutions of amorphous colorless poly (vinyl methyl ether) polymer with low level of impurities from purified vinyl methyl ether. The polymer has relatively high molecular weight, narrow molecular weight distribution and does not degrade readily due to the presence of impurities. The purification of the monomer uses a procedure selected from the group consisting of a vapor-liquid separation, a solid-liquid separation and combinations thereof to remove the impurities at a temperature within the range of from -20.degree. C. to +30.degree. C. The aqueous solution is prepared by devolitilization of solvent solutions of the polymerized purified vinyl methyl ether monomer. The solid polymer is prepared by heating the aqueous solution of the poly(vinyl methyl ether). The amorphous polymers of poly(vinyl methyl ether) are particularly suited for adhesive applications.
