SEPARATING DEVULCANIZED RUBBER

摘要

A method for separating a polymer from carbon black in devulcanized rubber, the method comprising steps of inserting devulcanized rubber into a bath of a solvent, dissolving a polymer out of the devulcanized rubber and into a solution of the solvent and the polymer, removing the solution from the bath without disturbing an un-dissolved residue comprising carbon black, and recovering the un-dissolved residue.
