摘要：

A catalyst system composed of CpTiCl3 with MAO proceeded the living polymerization of 1,3-butadiene at -25 degrees C to yield cis-polybutadiene (85% cis-content) with extremely narrow MMD (M-w/M-n = 1.04). The reaction temperature affected the cis-selectivity and living nature of the polymerization of 1,3-butadiene.
