ABSTRACT:
Additives for rubber compositions, giving vulcanizates having improved retention of optimum physical properties, are compounds having the formula R-S-B-S-R where B is an organic bridging group and R is an electron-withdrawing group, for example CN, CCl.sub.3, a radical containing an activated methylene group linked to the sulphur atom or the enolic tautomer of a keto-activated methylene group. Also useful as stabilizing agents are oligomeric analogues of such compounds.
