A CATALYST SYSTEM AND ITS USE IN A POLYMERIZATION PROCESS

摘要

The invention provides new polymerization catalyst activator compositions including a non-coordinating or ionizing activator having a siloxane moiety. The invention also provides a new supported catalyst activator composition where the siloxane moiety reacts with an alkylaluminum bonded to a silica support. The invention also provides for methods of making the activator compositions, polymerization catalyst systems including the activator compositions and processes for polymerizing olefin(s) utilizing same.
