## Abstract **Summary:** Isotactic polybutenes of variable isotacticity and melting points of form I in the range 100–125 °C have been prepared with both __C__~2~‐ and __C__~1~‐symmetric zirconocenes. The __C__~1~‐symmetric zirconocenes bearing the bilateral symmetric 2,5‐dimethyl‐7__H__‐cyclopenta

## 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
## Abstract 1‐Butene polyinsertion promoted by two typical __C__~2~‐symmetric zirconocene catalysts (i.e. __rac__‐ethylenebis(1‐indenyl)ZrCl~2~ (1) and __rac__‐dimethylsilylbis(1‐indenyl)ZrCl~2~) (2) was investigated under both hydrooligomerization and polymerization conditions and compared with th
