More Information
Summary:A copolymer contains monomer units (a) derived from a conjugated diene having 12 or fewer carbon atoms and monomer units (b) derived from farnesene. A method for producing the aforementioned copolymer involving copolymerization of at least conjugated dienes having 12 or fewer carbon atoms and farnesene. A rubber composition contains the copolymer (A), a rubber component (B) and carbon black (C). A rubber composition contains the copolymer (A), a rubber component (B) and silica (D). A rubber composition contains the copolymer (A), a rubber component (B), carbon black (C) and silica (D). A tire has at least one part where the rubber composition is used.
