Additives tor rubber compositions, giving vulcanisates 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, CCl3, 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 stabilising agents are oligomeric analogues of such compounds.
具有 R-S-B-S-R 式的化合物是橡胶组合物的添加剂,可使硫化胶更好地保持最佳物理性能,其中 B 是有机桥基,R 是抽电子基团,例如 CN、CCl3、含有与硫原子相连的活化亚甲基的自由基或酮活化亚甲基的烯醇同系物。 这类化合物的低聚类似物也可用作稳定剂。
