Title (EN) CROSSLINKED STYRENIC BLOCK COPOLYMER
(FR) COPOLYMÈRE SÉQUENCÉ STYRÉNIQUE RÉTICULÉ
Abstract:
(EN) 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.
(FR) L'invention concerne des compositions de copolymère séquencé styrénique (SBC) élastomère. Les compositions comprennent un ou plusieurs SBC et un ou plusieurs polymères miscibles avec des blocs d'extrémité styréniques de l'un ou des SBC, les compositions de copolymère séquencé étant à la fois physiquement et chimiquement réticulées, la réticulation chimique comprenant des liaisons covalentes entre des chaînes de SBC et la réticulation physique comprenant une interaction non covalente entre des blocs d'extrémité styréniques du ou des SBC et l'un ou les polymères miscibles avec les blocs d'extrémité styréniques. Les compositions de copolymère séquencé sont utiles pour former des articles d'immersion tels que des gants chirurgicaux.
