摘要： A method comprising synthesizing a cyclic organic compound via reaction of an unsubstituted or substituted cyclopentene with an unsubstituted or substituted acrylic acid in the presence of phosphoric and/or sulfonic acid reagent to make the cyclic organic compound. Also, a method of synthesizing a ligand for a transition metal, and a related substituted ligand-metal complex and catalyst, from the unsubstituted or substituted cyclopentene and unsubstituted or substituted acrylic acid. Also, the cyclic organic compound, ligand, and substituted ligand-metal complex and catalyst synthesized thereby. Also a method of polymerizing an olefin with the catalyst to give a polyolefin, and the polyolefin made thereby.

摘要： Catalyst systems and methods for making and using the same. A method of polymerizing olefins to produce a polyolefin polymer with a multimodal composition distribution, includes contacting ethylene and a comonomer with a catalyst system. The catalyst system includes a first catalyst compound and a second catalyst compound that are co-supported to form a commonly supported catalyst system. The first catalyst compound includes a compound with the general formula (C5HaR1b)(C5HcR2d)HfX2. The second catalyst compound includes at least one of the following general formulas: In both catalyst systems, the R groups can be independently selected from any number of substituents, including, for example, H, a hydrocarbyl group, a substituted hydrocarbyl group, or a heteroatom group, among others.

摘要： New bisindenyl ligand complexes and catalysts comprising those complexes. The invention is directed to improving the manufacturing of specific C1-symmetric bisindenyl complexes by modifying one of the indenyl ligands in order to improve the selectivity of the complex synthesis towards the desired anti-isomer, increase the yield and simplify the purification of the complex. The invention also relates to the use of the new bisindenyl metallocene catalysts for the production of polypropylene homopolymers or propylene copolymers.
