Abstract
This invention relates to a method for hydrogenation of poly(alkenyl aromatic) polymers or poly(alkenyl aromatic)/polydiene block copolymers that provides hydrogenated polymers with 99.5% or greater unsaturation and an MWD of less than about 3. Hydrogenated polymers and adhesives comprising the hydrogenated polymers and tackifier are also provided.
