Abstract: Methods of propylene polymerization incorporate bis biphenyl-phenoxy procatalysts favoring polypropylene isotacticity at elevated reactor temperatures. The methods include polymerizing propylene in the presence of a catalyst system to produce a propylene-based polymer. The catalyst system includes a metal-ligand complex selected from bis-biphenyl-phenoxy procatalysts. Polymerization reactions result in polypropylenes having greater than 90% isotacticity, as measured by percentages of isotactic triads, at reaction temperatures from 110° C. to 190 ° C. or from 160 ° C. to 190 ° C.
