Process for polymerizing conjugated dienes with lithium-tin-nitrogen initiators |
摘要 |
A method for preparing a polymer having low hysteresis loss value, good breaking properties and good processability with good productivity is provided by adding a tin compound during the propagation step of polymerization of a conjugated diene and/or an aromatic vinyl hydrocarbon. Polymers produced in accordance with this method have high molecular weight and star-shaped structures with branches having the same or different molecular weight.
