DECOMPOSITION METHOD OF VULCANIZED RUBBER, DECOMPOSED RUBBER RECOVERED BY IT, AND DECOMPOSED RUBBER COMPOSITION CONTAINING THE DECOMPOSED RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a method for decomposing a vulcanized rubber which enables to recover a denatured, polymeric decomposed rubber with good efficiency, and to provide the decomposed rubber recovered by it and a decomposed rubber composition containing the decomposed rubber.

SOLUTION: The decomposition method uses an organic solvent and a decomposition agent shown by formula (1) and/or formula (2). It is provided with a heating process wherein the decomposition agent and the vulcanized rubber are brought into a co-presence in the organic solvent and then heated to 100-200°C.
