  • Vicinal hydroxyl group containing copolymer and articles formed therefrom
    Patent number: 6562922
    Abstract: 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.
    Type: Grant
    Filed: March 23, 1999
    Date of Patent: May 13, 2003
    Assignee: Cryovac, Inc
    Inventors: Donald Albert Bansleben, Eric Francis Connor, Robert Howard Grubbs, William Peyton Roberts
  • Olefin polymerization catalysts and processes for making and using same
    Patent number: 6506704
    Abstract: 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.
