Abstract
Treatment of diene rubber with a diketo compound, in which the keto groups are part of a six-carbon hydrocarbon ring containing carbon-to-carbon unsaturation, or a tautomer of the compound, is performed at temperatures above 130.degree. C. Rubber compositions treated in this manner exhibit increased green strength, decreased plasticity, and, when vulcanized, decreased hysteresis.
