    Effect of Aminosilane Compounds as External Donors on Isospecific Polymerizations of 1-Butene with MgCl2/TiCl4/DIBP Catalyst

    Four aminosilane compounds were synthesized and employed as external electron donors for 1-butene polymerization with MgCl2 supported Ziegler-Natta catalyst. The four aminosilane compounds are di(piperidinyl)dime...

    Isospecific polymerizations of 1-butene catalyzed by MgCl2/TiCl4/internal donor-AlR3/external donor system

    1-Butene polymerizations were carried out by using a MgCl2/TiCl4/ID-AlR3/ED catalyst system in n-hexane, therein the internal donor (ID) is diisobutyl phthalate (DIBP), the external donor (ED) is diphenyl dimetho...
