| abstract |
The present invention relates to a self-assembled olefin polymerization catalyst comprising a transition metal compound according to formula (I) L q M m X n wherein M is a transition metal selected from the group consisting of Group 3-11 of the periodic table; X is independently selected from the group consisting of H, halogen, CN, optionally substituted N(R a ) 2 , OH, optionally substituted C 1 -C 20 alkyl, optionally substituted C 1 -C 20 alkoxy, wherein R a is independently selected from the group consisting of optionally substituted C 1 -C 20 alkyl, optionally substituted C 6 -C 20 aryl and halogen; q is an integer of at least 2; m is an integer of at least 2; n is an integer making (I) electrically neutral; L is independently a ligand which has at least two linked coordination units, wherein each coordination unit binds to a different transition metal. The present invention also relates to a process for the polymerization of olefins using the transition metal compound of the invention and to the polyolefins obtained from this polymerization process. Finally, the invention also relates to new ligands L present in the transition metal compound and to methods of making the ligand L. |
