To improve the strength of a diene rubber crosslinked by a re-bindable bond.SOLUTION: A crosslinked rubber contains a diene rubber having epoxy groups crosslinked with a dicarboxylic acid represented by the general formula (1) defined by HOOC-R1-COOH and an imidazole represented by the general formula (2) in the figure. In the formula (1), R1 represents a divalent hydrocarbon group having 3 to 50 carbon atoms which is optionally interrupted by one or more heteroatoms. In the formula (2), R2 represents a hydrogen atom or a methyl group.SELECTED DRAWING: None

    【課題】再結合性のある結合で架橋されたジエン系ゴムの強度を改良する。【解決手段】ゴム架橋物は、一般式(1)で表されるジカルボン酸と一般式(2)で表されるイミダゾールとで架橋されたエポキシ基を有するジエン系ゴムを含む。式(1)中のR1は、1個以上のヘテロ原子で中断されていてもよい、炭素原子数3~50の二価の炭化水素基を表す。式(2)中のR2は水素原子又はメチル基を表す。HOOC-R1-COOH (1)【化1】TIFF2025009300000009.tif29114【選択図】なし
