摘要：
Modified polybutadiene having a high-cis and low-trans structure with a moderate 1,2-structure content and exhibiting improved characteristics such as cold flow properties, which is obtained by modifying starting polybutadiene having a Tcp/ML1null4 ratio (Tcp: 5% toluene solution viscosity at 25null C.ML1null4: Mooney viscosity at 100null C.) of 2.5 or more in the presence of a transition metal catalyst.
