BRANCHED CONJUGATED DIENE COPOLYMER, RUBBER COMPOSITION AND PNEUMATIC TIRE |
摘要 |
There is provided a branched conjugated diene copolymer prepared by copolymerizing 1 to 99% by weight of a branched conjugated diene compound (1):
wherein R 1 is an aliphatic hydrocarbon having 6 to 11 carbon atoms, and 99 to 1% by weight of a conjugated diene compound (2):
wherein R 2 and R 3 are the same or different and each is a hydrogen atom, or the like. The branched conjugated diene copolymer is useful as a rubber component of a rubber composition for a tire enhancing both of abrasion resistance and grip performance to a high level and exhibiting excellent processability. |
