Abstract:
A rubber composition comprisinga crosslinked rubber particle comprising polymerized units of, (a1) 40 to 79.99% by weight of a conjugated diene monomer unit, (a2) 20 to 50% by weight of an aromatic vinyl monomer unit, and (a3) 0.01 to 10% by weight of a monomer unit having at least two polymerizable unsaturated groups with respect to 100% by weight of the total of (a1), (a2) and (a3), and a conjugated diene/aromatic vinyl copolymeric rubber wherein the vinyl bond content of the conjugated diene unit is 10 to 30% by weight and the 1,4-trans bond content exceeds 55% by weight.
