1997 CANADIAN SOCIETY FOR CHEMISTRY AWARD LECTURE RING-OPENING POLYMERIZATION (ROP) OF STRAINED METALLOCENOPHANES : THE DISCOVERY AND DEVELOPMENT OF A NEW ROUTE TO HIGH MOLECULAR WEIGHT POLY(METALLOCENES)

摘要: Ring-opening polymerization (ROP) of strained ring-tilted metallocenophanes can be achieved thermally, via anionic or cationic initiation, by the use transition-metal catalysts and provides access to a wide range high molecular weight (Mw = 10 5 n10 6 , Mn >1 0 ) poly(metallocenes). These materials possess variety interesting properties many are very easy prepare. This article an overview our work, giving background account initial discovery, discusses work on synthesis new poly(metallocenes) related with particular emphasis recent research directions.
