The present invention relates to a devulcanized rubber obtained by mixing a devulcanizing agent having an alkylsulfonamide group and a vulcanized rubber. The devulcanizing agent preferably contains a sulfonamide compound of an alkylamine having 12 or more carbon atoms. The present invention also relates to a rubber composition comprising the devulcanized rubber. The rubber composition preferably contains 1 to 30 parts by mass of the devulcanized rubber per 100 parts by mass of a total amount of an unvulcanized rubber component in the rubber composition.

A degradable elastomeric material that is formed from a composite blend of elastomeric particles in a continuous degradable binder. The degradable binder is generally a water-soluble binder which has a temperature dependent solubility in water and brine systems. Such degradable elastomers are particularly useful in the fabrication of degradable oil tools, among other applications.
