As the organic group, for example, a methyl group, l group, propyl group, butyl group, hexyl group, stearyl group or other chain type hydrocarbon group or a cyclopropyl group, cyclobutyl group, cyclohexyl group or other cyclic hydrocarbon group may be mentioned. Acs Surgery Principles And Practice.

Kane Sternheim Fisica Applicata. If this bonding performance is low, it leads to tire separation or other trouble.

An amine salt compound of a carboxylic acid containing a thermal dissociation portion having the Formula I:. Riso Ez U Service Manual. If the amount of the amine salt compound of a carboxylic acid having the formula I is small, the cross-linking efficiency deteriorates and the vulcanization rate becomes slower, and, therefore, this is not desirable, while conversely if it is great, scorching becomes easier, and, therefore, this is not desirable. The amine salt compound of a carboxylic acid group-containing disulfide according to the present invention i.

Furthermore, it is possible to use a compounding agent in a zinc oxide-free formulation according to the present invention and which is environmentally friendly. 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.

Further, the Mooney scorch time until the Mooney viscosity rose 5 points from V m was measured. Footnotes of Table I. Then, the vulcanization accelerator and sulfur were mixed to this master batch by an open roll to obtain the rubber composition. Math Makes Sense 5.

Accordingly, the object of the present invention is to provide a use 6527 agent for rubber vulcanization containing an amine salt compound of a carboxylic acid group-containing disulfide capable of improving the vulcanization speed and vulcanized rubber physical properties, without detrimentally affecting the scorch time, a method for producing the same and a rubber composition containing the same. The amounts of these additives may be made the conventional generally used amounts so long as they do not adversely affect the object of the present invention.

The amine salt compound of a carboxylic acid containing a thermal dissociation portion having the formula I according to the present invention is useful as a compounding agent for rubber vulcanization, specifically as a cross-linking agent, vulcanization accelerator and an acid acceptor.
