Summary: | Provided are: a modified vinylaromatic copolymer having reactivity and solubility which make the copolymer usable in producing copolymer rubbers; and a copolymer rubber material obtained from the modified vinylaromatic copolymer and having all of processability, strength, and homogeneity. This modified vinylaromatic copolymer is characterized by comprising structural units (a) derived from a divinylaromatic compound and structural units (b) derived from a monovinylaromatic compound, at least some of the structural units (a) being crosslinking structure units (a1), and by including an end modified with a modification group having at least one functional group selected from the group consisting of amino, hydroxyl, and alkoxysilyl groups. |
