Patent application numberDescriptionPublished
20110098425Catalyst Compounds and Use Thereof - This invention relates to Group 4 catalyst compounds containing di-anionic tridentate nitrogen/oxygen based ligands. The catalyst compounds are useful, with or without activators, to polymerize olefins, particularly a-olefins, or other unsaturated monomers. Systems and processes to oligomerize and/or polymerize one or more unsaturated monomers using the catalyst compound, as well as the oligomers and/or polymers produced therefrom are also provided.04-28-2011
20110098427Catalyst Compounds And Use Thereof - Group 4 catalyst compounds containing di-anionic tridentate nitrogen/oxygen based ligands are provided. The catalyst compounds are useful, with or without activators, to polymerize olefins, particularly α-olefins, or other unsaturated monomers. Systems and processes to oligomerize and/or polymerize one or more unsaturated monomers using the catalyst compound, as well as the oligomers and/or polymers produced therefrom are also provided.04-28-2011
