Abstract:
A rubber composition, comprising:(1) a crosslinked rubber particle containing as repeating units (a) 39.89 to 79.89% by weight of a conjugated diene unit, (b) 20 to 60% by weight of an aromatic vinyl unit, (c) 0.01 to 10% by weight of a monomer unit having at least two polymerizable unsaturated groups, and (d) 0.1 to 30% by weight of a monomer unit having one polymerizable unsaturated group and an amino group; wherein a total amount of (a), (b), (c) and (d) is 100% by weight; and (2) a conjugated diene/aromatic vinyl copolymeric rubber whose conjugated diene unit has a 1,2-vinyl content of 10 to 30% and a 1,4-trans content exceeding 55%.
