Polymer composition manufacturing method |
abstract |
Provided is a method of producing a polymer composition that has satisfactory processability, and when containing a filler, has satisfactory dispersibility of the filler, and that is suited for the production of a crosslinked polymer (tire) excellent in low hysteresis loss property. The method of producing a polymer composition according to the invention includes: a first step of kneading (A) a conjugated diene-based polymer that is a polymer of a conjugated diene compound or a copolymer of a conjugated diene compound and an aromatic vinyl compound, and is a reaction product between an active polymerization end and a compound represented by any one of the general formulae (1) to (3), and (B) a basic compound having an acid dissociation constant of 8.0 or more; and a second step of kneading a kneaded product obtained in the first step and a crosslinking agent. |
