A kind of method for preparing the modified polymer based on conjugated diene is disclosed, including:(a) in the presence of hydrocarbon solvent, use the compound represented by chemical formula 1, it polymerize conjugate diene monomer, or conjugate diene monomer polymerize with aromatic vinyl monomer, so as to form the living polymer with alkali metal end, and (b) makes compound of the living polymer with being represented by chemical formula 2 be coupled or react. |
