PROBLEM TO BE SOLVED: To provide a method for controlling sulfide bond forms in the higher order structure of a vulcanized rubber and in the hierarchical structure including ununiformity, or the proportion of the sulfide bond forms, as well as the physical properties of the vulcanized rubber.SOLUTION: The present invention provides a method for controlling sulfide bond forms in a vulcanized rubber, when producing it. The method includes the step in which: (i) compounds having carboxyl groups, and zinc oxides, or, (ii) zinc salts of compounds having carboxyl groups, are mixed, or mixed and heated, in a rubber, to produce compounds having carboxylic acid anions, and zinc, and the amount of at least one of them is controlled.SELECTED DRAWING: None
