Therefore, a polysulfide compound is inferior to a disulfide compound in the heat stability, and, therefore, has the problem that it easily reacts with sulfur and other vulcanization agents or rubber etc. Vw Polo Manual.

Vw Rcd Dab Owners Manual. The Hobbit Jrr Tolkien. The larger this value, the higher the bonding strength shown. A Course In Linear Algebra.

If the amount of this amine salt compound of a carboxylic acid group-containing disulfide compound I is small, the hardness becomes insufficient, and, therefore, this is not preferable, while conversely if large, the elongation at break becomes insufficient, and, therefore, this is not preferable.

For a breaker cushion rubber composition, a rubber composition and a tire ply topping. The rubber composition of the present invention may kis use, as another vulcanization accelerator, for example, a sulfenamide-based, thiuram-based or thiazole-based vulcanization accelerator.
