RUBBER COMPOSITION, RUBBER COMPOSITION FOR TIRE SIDEWALL, CROSSLINKED RUBBER COMPOSITION, AND TIRE

摘要

The present invention provides a rubber composition that is used for manufacturing a rubber excellent in weather resistance, fracture resistance and crack growth resistance, and that contains a conjugated diene compound/non-conjugated olefin copolymer, a conjugate diene-based polymer and a non-conjugated diene compound/non-conjugated olefin copolymer, a rubber composition for tire side use using the rubber composition for tire sidewall members, a crosslinked rubber composition obtained by crosslinking the rubber composition, and a tire. The rubber composition includes: (A) a conjugated diene compound/non-conjugated olefin copolymer containing a conjugated diene compound-derived unit by at least 40 mol%; (B) a conjugated diene-based polymer; and (C) a nan-conjugated diene compound/non-conjugated olefin copolymer containing an ethylene-propylene-diene rubber.
