摘要:
A method for preparing cis-1,4-polydienes having useful resistance to cold flow, the method comprising the steps of preparing a polymerization system including a reactive polymer by introducing a lanthanide-based catalyst and a conjugated diene monomer and adding a Lewis acid to the polymerization system including a reactive polymer.
