PROBLEM TO BE SOLVED: To reduce a monofunctional thiuram compound containing the compound, which can be synthesized at low cost and can be used as a vulcanization accelerator which gives an excellent curing rate without causing a high degree of scorch. Provided are a cured rubber composition exhibiting compressive permanent strain, improved aging curing properties, and oxidation resistant cross-linking. SOLUTION: A monofunctional thiuram compound has a structural formula: [In the formula, R 1 and R 2 may be the same or different and represent organic radicals, where R 1 and R 2 contain a total of at least 8 carbon atoms and R 1 and R 2 are together. Can be attached to to form a cyclic structure, where R 3 represents an organol radical containing at least 6 carbon atoms]. [Selection diagram] None |
