Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

An organometallic compound is incorporated into a vulcanized rubber matrix. A tunable, multi-phase copper sulfide lattice is compounded within an existing sulfur cross-linked morphology, as in crumb rubber obtained from recycled tires or other vulcanized rubber, whereby thermotropic properties of the rubber matrix are modulated. The process involves breaking of sulfur-sulfur and/or sulfur-carbon bonds through action of the carbon sulfide. The resulting rubber is suitable for use in applications typically utilizing virgin rubber, such as new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications. In other embodiments, an organometallic compound comprising iron acetate or alkaline earth metal acetate is incorporated into the vulcanized rubber matrix.

Provided is a desulfurized rubber capable of producing a crosslinked rubber having an excellent mechanical strength. The desulfurized rubber contains a solvent-soluble rubber component A having a weight-average molecular weight of more than 260,000 and less than 600,000, and a solvent-insoluble rubber component B, wherein the content ratio of the rubber component B is less than 45% by mass of the total mass of the content a of the rubber component A and the content b of the rubber component B.
