Abstract

Disclosed is an elastomeric hydrogenated block copolymer capable of being directly extruded or molded with a minimum of additives and having both high elasticity and low permanent set. The hydrogenated block copolymers have high melt flows allowing for ease in processing the hydrogenation block copolymers in melt processes such as extrusion and molding.
