ABSTRACT:
Modified rubber compositions are described which comprise at least one polymer rubber containing carbon-carbon unsaturation, at least one aromatic furazan oxide, and at least one hydrocarbon-soluble transition metal salt. When a transition metal salt is included in such polymer rubber formulations containing aromatic furazan oxides, the undesirable odors which normally characteristic of such rubber formulations is diminished or eliminated without significantly reducing the other desirable characteristics of the vulcanized rubbers. For example, filled vulcanizates made by vulcanizing mixtures in accordance with the invention exhibit high rebound, and tires which are formulated to include at least a portion of the cured vulcanizates in the tread exhibit reduced rolling resistance. Preferably, the hydrocarbon-soluble transition metal salts are the aliphatic or alicyclic monocarboxylic acid salts or cobalt, iron, nickel or manganese.
