Hafnium metallocene compound |
| abstract |
A very efficient catalyst system for the polymerization of 1-olefins consists of an aluminoxane and a metallocene which is a compound of the formula I ##STR1## in which R 1 and R 2 denote hydrogen atoms, halogen atoms or hydrocarbon radicals and R 3 and R 4 are mononuclear or polynuclear hydrocarbon radicals which can form a sandwich structure with the central atom and which are linked to one another by a --R 6 m --R 5 --R 7 n -- bridge containing a hetero atom and consisting of one or several members. n The catalyst system produces polymers having a high molecular weight. |
