MIXED DONOR SYSTEM FOR HIGH MELT FLOW AND HIGH ACTIVITY
摘要:
Disclosed are catalyst systems and methods of using the same for the polymerization of an olefin containing a solid titanium catalyst ant two external electron donors. Use of an aminosilane and an alkylsilane as external electron donors provide for high hydrogen response, high isotacticity, and high activity.
