METHOD FOR POLYMERIZATION AND COPOLYMERIZATION OF PROPYLENE

摘要

PURPOSE: A polymerization and copolymerization of propylene is provided to obtain propylene polymer and copolymer with excellent flowage through a simple process. CONSTITUTION: A propylene is polymerized or copolymerized under the presence of: a solid complex titanium catalyst containing magnesium, titanium, halogen and inside electron donor as a main catalyst; and group II and III organic metal compound as a co-catalyste; and one or more aminosilane compound selected from compounds denoted by R^1R^2NSiR^3(OR^4)_2 as an external electron donor.
