Abstract:
An elastomer composition comprising an elastomer having a functional group and a compound having a functional group, wherein:(1) a cross-link, which is formed by a hydrogen bond, is formed at around room temperature and cleaved reversibly between the functional group of the elastomer and the functional group of the compound at a temperature higher than room temperature by heating; (2) the hydrogen bond is formed by a hydroxyl group, and/or a primary or a secondary amine group, and a tertiary amine group, and/or a carbonyl group; and (3) in the elastomer composition the mixing ratio of the compound is 0.1-5 equivalent weights with respect to 1 equivalent weight of a reactive portion in the elastomer capable of forming the hydrogen bond.
