  Cs-symmetric hafnocene complexes for synthesis of syndiotactic polypropene

  摘要：

  Three new C-s-symmetric ansa-hafnocene complexes such as dichloro[eta(10)-2,4-cyclopentadienyl-1-ylidenebis(4-methyldiphenylmethylen)[2,7-bis(1,1-di-methylethyl)-9H-fluorene-9-ylidene]]hafnium (2) were synthesized which produce partiell syndiotactic polypropylenes with very high molecular weights. The influence of the methyl and methoxy substitution in the bridge was studied on the activity, tacticity, and molar mass. The hafhocene-MAO catalysts (1-4) were active up to polymerisation temperatures of 90 degreesC and produces 55 000 kg polymer in 1 h by 1 mol of hafnocene. The molecular weight of the obtained elastic polypropylene reaches 2.2 million g mol(-1). (C) 2003 Published by Elsevier B.V.

  Seventeen new catalyst. precursors for the syndiospecific polymerization of propylene are presented. The new metallocene complexes are substituted in the positions 2 and 7 of the fluorenlidene fragment by MeO-, halogen-, alkyl- and aryl groups. The focus is directed on effective new synthetic routes to substituted fluorenes and the preparation of Be catalyst precursors. In addition first polymerization results are reported.
