## Abstract **Summary:** Isotactic polybutenes of variable isotacticity and melting points of form I in the range 100β125βΒ°C have been prepared with both __C__~2~β and __C__~1~βsymmetric zirconocenes. The __C__~1~βsymmetric zirconocenes bearing the bilateral symmetric 2,5βdimethylβ7__H__βcyclopenta
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
A coordination polymerization of alkoxyallenes (2a-2f) by the [q3-(allyl)NiOCOCF3] (1) /PPh, system was carried out to obtain a polymer (3) bearing exomethylenes on the main chain. The structure of the obtained polymer was confirmed by 'H-, "C-NMR and IR spectra, and was revealed to consist of two u
