    摘要: The present invention provides a method for synthesizing a polybutadiene more efficiently and stably which is possible to obtain a rubber composition and a tire excellent in durability (fracture resistance, wear resistance and crack growth resistance). A method for producing a polybutadiene, where a butadiene monomer is polymerized with the existence of rare-earth element compounds represented by the following formula (i): M-(NQ)1(NQ)2(NQ)3  (i) (in the formula, M is at least one selected from lanthanides, scandium and yttrium; (NQ)1, (NQ)2 and (NQ)3 are amide groups which may be the same or different to each other, and have M-N bonds).

    摘要: The present invention provides rubber compositions for tires capable of providing tire components and pneumatic tires having low-temperature properties and abrasion resistance that are equivalent to those of tire components and pneumatic tires formed from conventional synthetic rubber, respectively, while meeting the demand for a sound material-cycle society. The present invention relates to rubber compositions for tires containing a biomass-derived rubber obtained by polymerizing a biomass-derived monomer component, the biomass-derived rubber having a pMC (percent modern carbon) value of 1% or greater as determined in conformity with ASTM D6866-10, and having a Tg (glass transition temperature) value of −120° C. to −80° C.
