摘要

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 one or more sbcs, the block copolymer compositions being both physically and chemically cross-linked, where the chemical cross-linking comprises covalent bonds between sbc chains and the Physical crosslinking comprises a non-covalent interaction between styrenic end blocks of one or more sbcs and the one or more miscible polymers with the styrenic end blocks. block copolymer compositions are useful in forming immersion articles such as surgical gloves.
