Extremely narrow-dispersed high molecular weight polyethylene from living polymerization at elevated temperatures with o-F substituted Ti enolatoimines
With a new titanium imineenolato complex, ethylene is polymerized in an unprecedented living fashion affording a polymer with a high molecular weight (M-n > 10(5) g mol(-1)) and an extremely narrow distribution (M-w/M-n 1.01) at the time; the living character is also retained even at an elevated temperature of 75 degrees C, and blockcopolymers are accessible.
