New Half-Sandwich Titanocenes for the Polymerization of Butadiene

  • Conference paper
Organometallic Catalysts and Olefin Polymerization

Abstract

Different half-sandwich titanium Chlorides and -fluorides were synthesized and used as catalysts in combination with methyl aluminoxane for the polymerization of 1,3-butadiene. Highest activities were obtained by using 1,3-dimethylcyclopenta-dienyl-titanium compounds and an aluminum/titanium ratio of about 700. The polybutadiene shows a technical useful microstructure with about 80 % 1,4-cis, 1 % 1,4-trans and 19 % 1,2-linked units. The catalyst used and the polymerization temperature can influence the microstructure. The molecular masses of the polybutadienes are very high (> 1 million g/mol).
