The present invention is directed to certain novel late transition metal salicylaldimine chelates and, further, to novel bidentate ligand compounds of substituted salicylaldimine, and their utility as polymerization catalysts alone or in combination with adjunct agent and/or Lewis base in processes of polymerizing olefin monomers and copolymerizing olefin monomers with functionalized olefin monomers.

The present invention is directed to vicinal hydroxyl-functionalized hydrocarbon polymers having a mole ratio of methylene to hydroxyl group of greater than 1 and to films, coatings and articles useful in packaging applications containing said polymers.

Vicinal hydroxyl group containing copolymer and articles formed therefrom

A process for forming neutral late transition metal chelates useful as polymerization catalysts comprising contacting a bidentate ligand forming compound that is free of electron-withdrawing groups with a di(tertiary amine) late transition metal reagent in the presence of an inert liquid, an olefinic monomer or a polar liquid selected from nitrites, ethers, aromatic heterocyclic amines, alcohols, nitroalkanes, nitroaromatics or mixtures thereof. The process provides a solid product or a solution of a storage stable transition metal bidentate ligand containing catalyst product which remains active for an extended storage period. Alternately, the present process can be conducted in situ in a polymerization zone of olefinic polymerization.

Olefin polymerization catalysts and processes for making and using same

A new and novel linear, regio-regular vicinal functionalized polymer methods of forming the same are described. The polymer has a linear hydrocarbon polymer backbone with vicinal functional groups having oxygen and/or nitrogen atom containing groups, such as hydroxy, carboxylic acid or ester, carbonyl acetate, amide, nitrile and the like, pendent from the polymer backbone chain in a regio-regular manner.

Regio-regular copolymer and methods of forming same

A composition capable of scavenging oxygen composed of (i) a copolymer of, at least, ethylene and a strained, cyclic alkylene, preferably cyclopentene; (ii) a transition metal catalyst; (iii) preferably, a photoinitiator; and (iv) optionally, a polymeric diluent.

Oxygen scavenging composition with improved properties and method of using same

The present invention is directed to Packaging Materials and Packaging Articles having a structure composed of a substantially linear, regio-regular functionalized hydrocarbon polymer having C,-C,hydrocarbon polymer repeating units wherein each unit has at least one functional group uniformly pendent therefrom.

Regio-regular functionalized polymeric packaging material

Non-ionic bidentate late transition metal chelates tethered to an inert support by a covalent bond group to provide a catalyst useful in slurry and gas phase polymerization of olefins.

Supported catalysts and olefin polymerization processes utilizing same

Non-ionic late transition metal chelates of salicylaldimine and pyrrolaldimine can be tethered to an inert support by a covalent bond to provide a catalyst useful in slurry and gas phase polymerization of olefins.

Substantially linear vinylene carbonate/1-olefin copolymers, a process of forming the same, and packaging materials incorporating the same are described. These copolymers are formed by reacting the component monomers in the presence of a single component, non-ionic polymerization catalyst at relatively low temperatures and pressures.

Linear vinylene carbonate/1-olefin copolymer and articles formed

New shrinkage control agents, for unsaturated polyester resin systems, which are copolymers of vinyl versatate and vinyl acetate, i.e., poly(vinyl versatate-co-vinyl acetate). The shrink control agents are useful both with neat and filled unsaturated polyester resin systems. The shrink control agents are especially useful under conditions where the unsaturated polyester resin system is cured at or below ambient temperatures.

Shrink controlled low-temperature-curable polyester resin compositions

A method of preparing phosphonate compositions comprising di-(phosphonomethyl) formal is disclosed which comprises (a) forming an intimate mixture of hydroxymethylphosphonic acid and formaldehyde or its condensates, said mixture having a least about 0.5 equivalents of formaldehyde per equivalent of hydroxymethylphosphonic acid; and (b) subjecting said intimate mixture to a temperature of between about 100.degree. C. and 180.degree. C. for a time sufficient to allow the components to react to form a reacted mixture comprising di-(phosphonomethyl) formal. Di-(phosphonomethyl) formal, phosphonate compositions wherein at least about 20 more % of the phosphonate groups are present as di-(phosphonomethyl) formal, and phosphonate compositions which comprise hydroxymethylphosphonic acid and di-(phosphonomethyl) formal such that the mole ratio of phosphonate groups present as di-(phosphonomethyl) formal to phosphonate groups present as hydroxymethylphosphonate is at least about 1:3, as disclosed, may be used for corrosion inhibition in aqueous systems.
