Abstract
A titanium complex having fluorine-containing phenoxyimine chelate ligands, when activated with methylalumoxane (MAO), promotes a highly stereospecifi c living polymerization of propylene at room temperature to produce syndiot actic polypropylene (rr = 87%, T-m = 137 degreesC) having extremely nar row polydispersity (M-w/M-n = 1.11).
