Stabilization of guayule-type rubbers

摘要

A stabilizing composition and process for guayule type rubbers which can be directly applied to guayule-type plants or shrubs before processing thereof, or to guayule-type rubber miscella, rubber-resin miscella, etc, contains a volatile low melting point antioxidant which is either liquid or solid and an optional liquid inert carrier which lowers the melting point of the antioxidant. Since antioxidants are generally expensive, recovery thereof as by distillation is aided through the utilization of low boiling point antioxidants.
