Abstract
Treatment of diene rubber with a compound of the formula ##STR1## wherein X and Y are --OH or --NH.sub.2 and R and R' are hydrogen, --OH, NH.sub.2 or non-reactive substituents 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.
