Abstract

The cationic ring-opening polymerization of 2-methyl-2-oxazoline and 2-phenyl-2-oxazoline was efficiently used using bis(η5- cyclopentadienyl)dimethyl zirconium, Cp2ZrMe2, or bis(η5-tert-butyl-cyclopentadienyl)dimethyl hafnium in combination with either tris(pentafluorophenyl)borate or tetrakis(pentafluorophenyl)borate dimethylanilinum salt as initiation systems. The evolution of polymer yield, molecular weight, and molecular weight distribution with time was examined. In addition, the influence of the initiation system and the monomer on the control of the polymerization was studied.
