| titleOfInvention | Olefin polymerization catalysts |
| abstract | The invention concerns olefin polymerization catalyst component comprising an organometallic compound of general formula Iwherein:M is a transition metal of groups 3, 4-10, lanthanide or actinide of the periodic table of the elements; each R is independently a structural bridge rigidly connecting two ligands L1, L2 and L3 and is constituted by 1 to 4 chain atoms selected from carbon, silicon, germanium, oxygen, boron; m, n and o are 0 or 1, with the proviso that m+n+o is 2 or 3; L1 is a ligand of the cyclopentadienyl type or is isolobal to cyclopentadienyl, L2 is a ligand of the cyclopentadienyl type or is isolobal to cyclopentadienyl, or a monovalent anionic ligand selected from the group consisting of N, P, B when m+n=2, it is selected from the group consisting of NR<1>, PR<1>, BR<1>, O and S when m+n=1;L3 is a monovalent anionic ligand selected from the group consisting of N, P, B when n+o=2, it is selected from the group consisting of NR<1>, PR<1>, BR<1>, O and S when n+o=1; R<1 >is hydrogen, C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C3-C20 alkenyl, optionally comprising 1 to 5 hetetoatoms such as Si, N, P, O, F, Cl, Br; each X is independently selected from the group consisting of hydrogen, halogen, NR<2>2, R<2 >with R<2 >equal to C1-C20 alkyl, C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C3-C20 alkenyl, optionally comprising 1 to 5 heteroatoms such as Si, N, P, O, F, Cl, Br; q is a number whose value is: 0, 1, 2 or 3, depending on the valence of the metal M; D is a neutral Lewis base, p is a number whose value is: 0, 1, 2 or 3.The invention also concerns catalysts comprising compounds of formula (I) and the polymerization process making use of a catalyst comprising the claimed compounds. |
