Abstract

With a new titanium imineenolato complex, ethylene is polymerized in an unprecedented living fashion affording a polymer with a high molecular weight (Mn > 10(5) g mol-1) and an extremely narrow distribution (Mw/Mn 1.01) at the same time; the living character is also retained even at an elevated temperature of 75 degrees C, and blockcopolymers are accessible.
