摘要： The present invention relates to a novel catalyst for diene polymerization comprising a heteroleptic single-molecule aluminum compound and a cobalt compound having a carboxyl group with a predetermined proportion and a method for preparing polybutadiene from 1,3-butadiene using a catalyst for diene polymerization.The novel catalyst of the present invention, which comprises a heteroleptic single-molecule aluminum compound with a huge stereostructure and a cobalt compound, has a stabilized catalytic active site without the need of adding a special material for controlling the activity of cobalt, such as water, phenol, alcohol, and phosphorus compound, and has good activity without a catalyst aging process since the reduction of cobalt is minimized. Consequently, the catalyst may be used to polymerize 1,3-butadiene to obtain polybutadienes having cis and trans structures with good yield and narrow molecular weight distribution.
