  • METHODS FOR PREPARATION OF PROPYLENE POLYMERS
    Publication number: 20140121337
    Abstract: Disclosed herein is a polymerization method of propylene, which can prepare a propylene homopolymer with both high fluidity and high rigidity as well as a propylene/?-define copolymer having both high fluidity and a good rigidity-toughness balance by, for example, control of polymerization steps and elevation of polymerization temperature, while the catalyst still maintains a relatively high polymerization activity.
