Fund Project: We thank very much for the financial support of the National Natural Science Foundation of China (No. 20574003 (XK100100433,XK100100540),Polymer Chemistry and Physics,BMEC).

Polybutene-1 was synthesized stereoselectively with the precursor η⁵-(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 ¹³C NMR and WAXD.
