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.

The product was filtered and washed with acetone two times and dried to nis a white powder compound A having the following formula in Capri V6 Repair Manual. Holden Jackaroo Workshop Manual A method for producing an amine salt compound of a carboxylic acid containing a thermal dissociation portion represented by the Formula I according to claim 1 comprising the step of reacting a carboxylic acid II and an amine III under the following reaction scheme:.
Among these, from the viewpoint of the high solubility with respect to disulfides, thiols and amines and the ease of removal of reaction products, aliphatic alcohols, ethers and ketones are preferable. Compounding silica-reinforced rubber with low volatile organic compound VOC emission. After the reaction ended, the methanol was removed in vacuo. Electric Power Engineering Handbook Electrical. In accordance with the present invention, there is provided a compounding agent for rubber vulcanization containing an amine salt compound of a carboxylic acid group-containing disulfide having the formula I wherein, in the above formula IX is an aromatic group.
To provide a compound which has a higher vulcanization efficiency and superior heat aging resistance compared to conventional compounding agents for rubber compositions and which is environmentally friendly. Cournot S Model Of Oligopoly. These may be used alone or may be used in 6527 combination thereof.

Bmw 3 Series E The results are shown in Table I. R 1 and R 2 may, together with the nitrogen atoms they bond with, form a heterocyclic group, for example, imidazole group, triazole group, pyrazole group, aziridine group, pyrrolidine group, piperidine group, morpholine group, thiomorpholine group or other group. Audi A4 B5 Repair Manual.
As specific examples of the aryl group, for example, a phenyl group, naphthyl group, etc.
Power Plant Engineering Rajput. As the other diene-based rubber usable in the present invention, any diene-based rubber capable of compounding in a rubber composition for tire can be used. Compound A synthesized by Preparation Example 1. Awaken The Giant Within Arabic. As examples of the organic groups, a methylene group, ethylene group, propylene group, hexylene group, cyclobutylene group, cyclohexylene group, phenylene group, thiazole group, thiadiazole group, pyridilene group, naphthylene group, etc.
