Abstract:
A rubber composition for tire side wall, comprising:(A) an unsaturated olefin copolymer prepared from(i) ethylene,(ii) an aromatic vinyl compound,(iii) a non-conjugated polyene, and optionally(iv) an .alpha.-olefin having 3 or more carbon atoms, in which the molar ratio [(i)/(iv)] of constitutent units derived from ethylene (i) to constituent units derived from the .alpha.-olefin having 3 or more carbon atoms (iv) is in the range of from 100/0 to 40/60, the molar ratio [((i)+(iv))/(ii)] of the sum of constituent units derived from ethylene (i) and constituent units derived from the .alpha.-olefin having 3 or more carbon atoms (iv) to constitutuent units derived from the aromatic vinyl compound (ii) is in the range of from 98/2 to 60/40, the intrinsic viscosity [.eta.] measured in decalin at 135.degree. C. is in the range of from 1.0 to 6.0 dl/g, and the iodine number is in the range of from 10 to 50; and(B) a diene rubber.
