ABSTRACT:
By reacting a diene polymer having nitrile groups with an anti-deteriorating agent having at least one polar group selected from the group consisting of amino group and imino group in the presence of a catalyst, a diene rubber can be obtained in which said anti-deteriorating agent is chemically combined to the nitrile groups. Said rubber per se has resistance to deterioration and, at the same time, acts as an anti-deteriorating agent for other diene rubbers. The chemically combined anti-deteriorating agent is not extractable with solvent, so that said rubber has a stable resistance to deterioration and a stable anti-deteriorating action on other diene rubbers.
