Abstract

See full text

A sulfur-containing cycloaliphatic compound, useful as a crosslinker for filled sulfur-vulcanizable elastomer compositions, is represented by the general formula:

description='In-line Formulae' end='lead'G[-CaH2a—S[C(═O)]bR]n description='In-line Formulae' end='tail'

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, andsaturated monocyclic silicone [RSiO—]n[R2SiO—]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.
