1. An elastomeric styrenic block copolymer (SBC) composition comprising one or more SBCs and one or more polymers having a molecular weight polydispersity index greater than 2.0 miscible with styrenic end blocks of the one or more SBCs;
wherein said block copolymer composition is both physically and chemically crosslinked;
wherein said chemical crosslinking comprises covalent bonds between chains of SBC and;
wherein said physical crosslinking comprises non-covalent interaction between styrenic end blocks of the one or more SBCs and the one or more polymers miscible with the styrenic end blocks.
