SULFUR-CONTAINING CYCLOALIPHATIC COMPOUND, PROCESS FOR ITS PREPARATION, FILLED SULFUR-VULCANIZABLE ELASTOMER COMPOSITION CONTAINING SAME AND ARTICLES FABRICATED THEREFROM

摘要

A sulfur-containing cycloaliphatic compound, useful as a crosslinker for filled sulfur-vulcanizable elastomer compositions, is represented by the general formula: G[—CaH2a—S—S(═O)b—R]n wherein G 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[R2SiO—]p group of valence n; each R independently is a 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 1 or 2; n is an integer of from 3 to 6; and p is an integer of from 0 to 3.
