Abstract: Methods for the hydrogenation of aromatic-containing polymers are described. A method includes hydrogenation of polymers by contacting a polymer solution that includes an aromatic-containing polymer and a mixture of a non-polar solvent and a polar solvent having a dielectric constant greater than 7.6 at 25° C. and a non-polar solvent having a dielectric constant of 5 or less at 25° C. with a hydrogenation catalyst to produce polymer composition that includes at least one hydrogenated and/or at least one partially hydrogenated aromatic ring. The polar to non-polar solvent volume ratio ranges from 10:90 to 80:20.
