Abstract
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.
Claims25
A rubber composite structure having an unbound, reptated internal morphology, wherein a portion of rigid sulfidic linkages therein are each tethered at an original allylic carbocation and unbound at an original methyl carbocation.
A vulcanized rubber, wherein a portion of the rigid sulfidic linkages therein are each tethered at an original allylic carbocation and unbound at an original methyl carbocation, and wherein a portion of polymer backbones within the vulcanized rubber are substituted by an acetate moiety.
