| titleOfInvention | Preparation and use of heterogeneous catalyst components for olefins polymerization |
| abstract | Heterogeneous catalytic component obtainable by reacting a porous inorganic support with a metallocene compound characterized in that the metallocene compound is defined by the following general formulas: n nwherein: n L, equal to or different from each other, is selected from the group comprising: cyclopentadienyl, indenyl, tetrahydroindenyl, fluorenyl, octahydrofluorenyl or benzoindenyl; each R is independently selected from hydrogen, C 1 -C 20 alkyl, C 3 -C 20 cycloalkyl, C 6 -C 20 aryl, C 3 -C 20 alkenyl, C 7 -C 20 arylalkyl, C 7 -C 20 alkylaryl, C 8 - 20 arylalkenyl, linear or branched, optionally substituted by 1 to 10 halogen atoms, or a group SiR II 3 ; each R I equal to or different from each other is a divalent aliphatic or aromatic hydrocarbon group containing from 1 to 20 carbon atoms, optionally containing from 1 to 5 heteroatoms of groups 14 to 16 of the periodic table of the elements and boron; each Q is independently selected from B, C, Si, Ge, Sn; M is a metal of group 3, 4 or 10 of the Periodic Table, Lanthanide or Actinide; each X is independently selected from: hydrogen, chlorine, bromine, OR II , NR II 2 , C 1 -C 20 alkyl or C 6 -C 20 aryl; each R II is independently selected from C 1 -C 20 alkyl , C 3 -C 20 cycloalkyl, C 6 -C 20 aryl, C 3 -C 20 alkenyl C 7 -C 20 arylalkyl, C 7 -C 20 arylalkenyl or alkylaryl, linear or branched; R II is methyl, ethyl isopropyl; L′ is N or O; when L is cyclopentadienyl k is equal to 5, when L is indenyl k is equal to 7, when L is fluorenyl or benzoindenyl k is equal to 9, when L is tetrahydroindenyl k is equal to 11 and when L is octahydrofluorenyl, k is equal to 17; z is equal to 0, 1 or 2; x is equal to 1, 2 or 3; y is equal to 1, 2 or 3; x+y+z is equal to the valence of M; m is an integer which can assume the values 1, 2, 3 or 4; a and b are integers whose value ranges from 0 to k-1; f is an integer whose value ranges from 1 to k; g is 0 or 1; c and e are equal to 0 or 1; a+b+c is at least 1; a+g+c is at least 1; d is equal to 0, 1 or 2; when Q is B, then c+d=1; when Q is C, Si, Ge or Sn, then c+d=2; when L′ is N, then g+e=1; when L′ is O, then g=0 and e=0. |
