    • A crosslinked polysulfide-containing cycloaliphatic compound, useful as a crosslinker for filled sulfur-vulcanizable elastomer compositions, is represented by the general formula: [(C a H 2a -) m G 1 (-C b H 2b S x -) n-m and C c H 2c -G 2 - C d H 2d S y - ] p [R]q wherein G 1 is a saturated, monocyclic aliphatic group of valence n containing from 5 to 12 carbon atoms and optionally containing at least one halogen or a saturated monocyclic silicone [RSiO-] n [R 2 SiO-] r group of valence n; G 2 is a saturated, divalent cyclic aliphatic group of valence 2 containing from S to 12 carbon atoms and optionally containing at least one halogen or a saturated monocyclic silicone [RSiO-] n [R 2 SiO-] r group of valence n;; each R independently is a selected from the group consisting of a hydrogen atom, monovalent hydrocarbon of up to 20 carbon atoms and a halogen atom; each occurrence of subscripts a, b, c, d, m, n, o, p, q, x and y independently is an integer wherein a is 2 to 6; b is 2 to 6; c is 1 to 6; d is 1 to 6; m is 1 or 2; n is 3 to 5; o is a positive integer, p is 0 or a positive integer; q is a positive integer; r is an integer of from 0 to 3; x is 1 to 10 and y is 1 to 10, with the provisos that, (i) at least one x is 2 to 10; (ii) the ratio of p to o is less than 1 to 5; and q is equal to the sum of unfilled valences of the (C a H 2a -) m G 1 (-C b H 2b S x -) n-m and C c H 2c -G 2 - C d H 2d S y - groups.
