Extremely Narrow-Dispersed High Molecular Weight Polyethylene from Living Polymerization at Elevated Temperatures with o-F Substituted Ti Enolatoimines
摘要:
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.
