摘要：Disclosed are a polybutadiene having a controlled microstructure, a narrowmolecular weight distribution, minimal gel content, and a low APHA color, a modifiedpolybutadiene, producing methods for both, and a rubber-reinforced styrene resincomposition using the same. The polybutadiene of the present invention is characterizedin that the ratio (Tcp/ML1+4) of a 5% toluene melting viscosity (Tcp) measured at 25°Cand the Mooney viscosity (ML1+4) at 100°C is 2.0 or higher, the molecular weightdistribution (Mw/Mn) is 2.80 or less, the gel content is 0.06 wt% or less, and the APHAcolor is 20 or less.
