As catalysts for the Ziegler - Natta. Ziegler Natta catalysts reinforced and improved Balwmwksan alumoxane, methods of preparation, and processes for producing polymers thereof

摘要

Abstract: the present invention deals with a Awlyfyny olefin catalyst, methods for preparation of the catalyst activation at the site and the olefin polymerization monomer, for example, by the raw material. One worker, the catalytic reaction product a titanium tetrachloride titanium trichloride / second / magnesium chloride magnesium dichloride drive Hydrwfwran tetrahydrofuran.The catalyst activator present in situ in a polymerization reactor by the use of a catalyst catalyst based on Alalwmwksan alumoxane as conventional steps slow separation of the catalyst and promoter Before polymerization is disposed.Unexpected characteristics in accordance with the present invention is about characteristic increases in the productivity of the catalyst while maintaining a relatively constant value of the bulk density of materials Albwlymyryt pain Are we heading during the product associated with the product Albwlymyry contained on the distribution of molar site is compared with the factors of the catalytic Mytalwsynyt metallocene catalysts typical Alalwmwksan steroids.
