A sulfur-containing cycloaliphatic compound, useful as a crosslinker for filled sulfur-vulcanizable elastomer compositions, is represented by the general formula: G[-C a H 2a -S[C(=O)] b R] n wherein G is selected from the group consisting of: - saturated, monocyclic aliphatic group of valence n containing from 5 to 12 carbon atoms and optionally containing at least one halogen, and - saturated monocyclic silicone [RSiO-] n [R 2 SiO-] p group of valence n; wherein each R independently is a hydrogen or monovalent hydrocarbon of up to 20 carbon atoms; each occurrence of subscripts a and b independently is an integer wherein a is 2 to 6 and b is 0 or 1; p is an integer of from 0 to 3; and, n is an integer of from 3 to 6, with the provisos that when b is 0, R is a hydrogen atom, and when G is a non- halogenated, saturated monocyclic aliphatic group of 6 carbon atoms, n cannot be 3. |
