Radial hydrogenated block copolymers showing one phase melt behavior

1. Field of the Invention Radial block copolymers that exhibit one phase melt behavior at a temperature below the degradation temperature of the radial block copolymer. The radial block copolymers have a plurality of arms, wherein each arm has a numerical average molecular weight of from about 5,000 to about 30,000, each arm includes a monoalkenyl aromatic hydrocarbon block and a hydrogenated conjugated diolefin block, and the monoalkenyl aromatic hydrocarbon is preferably present in an amount of from about 10 wt % to about 40 wt % of the radial block copolymer. Also disclosed is a process for preparing the one phase melt block copolymers.
