The effect of polymerization conditions on crystalline of polybutene-1 catalyzed by metallocene catalyst
2007
Abstract Polybutene-1 was synthesized stereoselectively with the precursor η 5 -(pentamethyl-cyclopentadienyl) tribenzyloxide titanium (Cp*Ti(OBz) 3 ) and methylaluminoxane (MAO). The effects of polymerization conditions, trimethyl alumina (TMA) content in MAO and temperature on the crystalline and molecular weight of the products, and catalytic activity were investigated. The structural properties of the polybutene-1 were characterized with 13 C NMR and WAXD.
