摘要：

An isomerically pure, C2-symmetric Ni(II) complex was synthesized and found to be living for propylene polymerization. The regioselectivity of the catalyst varied greatly with reaction temperature, with regioregular, highly isotactic polypropylene (PP) produced at low temperatures, and regioirregular PP produced at high temperatures. Regioblock PP was formed by changing the reaction temperature during the polymerization. Copyright © 2005 American Chemical Society.
