摘要： The present invention relates to a catalyst of Formula (I) wherein R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, L1, M1, Q1 and Q2 have the meaning defined in the description and claims. The present invention also relates to a catalyst composition comprising at least one catalyst according to the invention. an optional activator: an optional support: and an optional co-catalyst. The present invention also relates to the use of a catalyst or catalyst composition according to the invention for the preparation of an olefin polymer. The present invention also relates to an olefin polymerization process. the process comprising: contacting a catalyst or a catalyst composition according to the invention, with an olefin monomer, optionally hydrogen, and optionally one or more olefin comonomers: polymerizing the monomer, and the optionally one or more olefin comonomers, in the presence of the at least one catalyst composition, and optional hydrogen, thereby obtaining an olefin polymer. The present invention also relates to olefin polymers and articles comprising said olefin polymer.

摘要： A process for preparing a long chain branched polypropylene in presence of two metallocene-based active catalyst systems is provided. The polypropylene obtained therefrom has new molecular architecture and improved elasticity properties. The polypropylene is further characterized by new signals in its 13C NMR spectrum.
