Olefin co-catalyst

Metallocene catalysts are catalytic systems consisting of metallocene compounds and co-catalysts, and their catalytic polymerization mechanism consists of the mutual formation of cationic catalytic activity centers by metallocene and co-catalysts.

Methylaluminoxane (MAO) and modified methylaluminoxane (MMAO) are used as efficient co-catalysts in metallocene and post-transition metal olefin polymerization catalysts with high catalytic activity. Metallocene polyethylene (mPE), metallocene polyolefin elastomers (POE), metallocene polyolefin lubricants (PAO) and metallocene polyolefin waxes, linear a-olefins (LAO), new materials such as cyclic polyolefins (COC/COP), ultra-high-molecular-weight polyethylene (UHMWPE), polystyrene (PS), metallocene ethylene propylene diene rubber (mEPDM), and other new materials synthesis with metallocenes. catalysts for the synthesis of new materials such as ultra-high molecular weight polyethylene (UHMWPE), polystyrene (PS), metallocene ethylene propylene rubber (mEPDM), etc.
