Abstract
The present disclosure provides a method comprising reducing the size of elastomeric particles in the presence of a liquid, wherein said liquid comprises an antidegradant and optionally a surfactant. Further provided is a method comprising bringing elastomeric particles into contact with a liquid, wherein said liquid comprises an antidegradant and, optionally, a surfactant. Also provided is an elastomeric particle that is created from an original elastomeric piece, where said elastomeric particle has an antidegradant concentration greater than that of the original elastomeric piece. Further provided is a rubber composition comprising the elastomeric particle. Additionally, the disclosure provides a tire containing a rubber composition that comprises the elastomeric particle.
