摘要：

(Chemical Equation Presented) A tactical approach: C3-chiral ancillary ligands such as tris (oxazolinyl) ethane allow stereocontrol in olefin polymerization (see scheme). An alkyl ScIII catalyst polymerizes 1-hexene with activities ranging from 2000 to 36000 kgmol-1 h -1 (at -30 to + 21°C) and good tacticity control at low temperatures. © 2005 Wiley-VCH Verlag GmbH & Co.
