共重合体ゴム及びその製造方法、並びに架橋ゴム組成物

Japanese Patent JP7144430

B2

Provided are a copolymer rubber that is workable, strong, and homogeneous, and is suitable as a resin modifier or the like; a crosslinked rubber composition having excellent mechanical strength, wear resistance, etc.; and a polyfunctional vinyl aromatic copolymer that is a superior raw material for the above. Polymer rubber obtained by copolymerizing raw materials including a polyfunctional vinyl aromatic copolymer (A), a conjugated diene compound (B), and an aromatic vinyl compound (C), the rubber being characterized in that: the polyfunctional vinyl aromatic copolymer (A) comprises a structural unit (a) originating from a divinyl aromatic compound, a structural unit (b) originating from a monovinyl aromatic compound, and a structural unit (c) originating from a tertiary amino group, including at least 2 mol% of structural unit (a), and at least some of structural unit (a) being present in the form of a vinyl-group-containing structural unit (a1); and the number-average molecular weight of the rubber is 300 to 100,000.
