US Patent 9458303 Recycling of styrene butadiene rubber and like materials

Present embodiments provide efficient and cost-effective use of chloramines such as monochloramine, NH2Cl, to degrade styrene butadiene rubber, a material from which tires and other products are made, so that it can be recycled, and do so by overcoming the limitations of monochloramine due to its thermodynamic instability by achieving and maintaining adequate monochloramine concentrations for the degrading process.
