Abstract
PURPOSE: To prepare a diene polymer of excellent curing characteristics and processability, having a small amount of difference of the Mooney viscosity of the raw rubber and that of the compound by polymerizing a conjugated diene with a vinyl aromatic compound in the presence of a polyvinyl aromatic compound and a specific catalyst by changing the polymerization temperature during the process.
