A thiocarbamoyldisulfanyl-functional cycloaliphatic compound, useful as a crosslinker for filled sulfur-vulcanizable elastomer compositions, is represented by the general formula: G[-CaH2a-S-S-C(=S)NR2]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 hydrogen or a monovalent hydrocarbon of up to 20 carbon atoms; each occurrence of subscripts a independently is an integer wherein a is 2 to 6; n is an integer of from 3 to 6; and, p is an integer of from 0 to 3.
一种含有硫代氨基二硫基的环脂化合物,通式为G[-CaH2a-S-S-C(=S)NR2]n,用作填充硫化橡胶组合物的交联剂。其中,G是一个饱和的、含有5到12个碳原子的价态为n的单环脂肪基,可以选择性地含有至少一个卤素或价态为n的饱和单环硅氧[RSiO-]n [R2SiO-]p基团;每个R独立地是氢或具有最多20个碳原子的一价碳氢化合物;每个下标a的出现独立地是一个整数,其中a为2到6;n是从3到6的整数,p是从0到3的整数。
