✦ Synopsis

Abstract

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.
