Abstract
The disclosure relates to a hydrogenated styrenic block copolymer with high vinyl content, low viscosity, low order-disorder temperature and improved processability. The hydrogenated styrenic block copolymers can be extruded or molded with a minimum of additives. The hydrogenated styrenic block copolymers have high melt flows allowing for ease in processing such as injection molding, overmolding, dipping, extrusion, roto-molding, slush molding, fiber spinning, film making, 3D printing and foaming.
