Abstract

3‐Methyl‐1‐butene was polymerized in the presence of a number of homogeneous metallocene catalysts (co‐catalyst methylalumoxane). Contrary to literature reports, it was found that even the simplest C~2~‐symmetric metallocenes promote the isotactic polymerization of this monomer with reasonable productivities. Quite surprisingly, a prevailingly isotactic polymer was also obtained in the presence of C~s~‐symmetric metallocenes, which are instead syndiotactic‐specific in propene polymerization.

Activation with AlMe at low temperature converts half-metallocene complexes of tantalum with methyl methacrylate (MMA) and diazadiene ligands such as [Cp\*Ta(η -Cy-DAD)(η -MMA)] (structure shown) into effective catalysts for the polymerization of MMA. Polymerization is complete after 10 min at -20°C

Selective polymerization of 1-butene in C 4 fractions has been investigated using a supported Ziegle~Natta catalyst. Catalytic activity depends on the pre-treatment of the C 4 cut as well as on the composition. Isobutene retards the polymerization. Tacticity of the polymers can be influenced by ethy
