METHODS AND CATALYST SYSTEMS FOR PRODUCTION OF ISOTACTIC POLYPROPYLENE

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...
