Kaminsky, Walter | Fernandez, Mercia
Oleic acid methyl ester can be converted by metathesis reaction in the presence of ethene into 1-decene and 9-decenoic acid methyl ester. Both components are suitable comonomers for the synthesis of polyolefin specialties by copolymerization with ethene or propene. For this copolymerization, metallocene/methylaluminoxane catalyst or other single-site catalysts are more active than classical Ziegler-Natta catalysts because they insert higher amounts of longer-chain α-olefins or olefins with polar groups. The microstructure of these copolymers can be tailored in a great variety using metallocene complexes with different symmetries.
