Elastomeric styrenic block copolymer (SBC) compositions are provided. The compositions comprise one or more SBCs and one or more polymers miscible with styrenic end blocks of the one or more SBCs, the block copolymer compositions being both both physically and chemically crosslinked, where the chemical crosslinking comprises covalent bonds between chains of SBC and the 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. The block copolymer compositions are useful in forming immersion articles such as surgical gloves.
