ABSTRACT:
An object of the present invention is to provide a curable composition which exhibits excellent toughness after the curing and excellent long term stability, as well as a rubber used in such curable composition. Such object is realized by a maleimide terminated rubber having maleimide structure on both ends of the molecule obtainable by reacting a rubber having amino group and/or imino group on both ends of the molecule and a bismaleimide compound, as well as a curable composition comprising such maleimide terminated rubber and a resin and/or a rubber other than such maleimide terminated rubber.
