Lightweight thermoplastic elastomer as a damping material for protectors

Abstract

The invention relates to a thermoplastic elastomer composition comprising the components: A1) a styrene-isoprene-styrene block copolymer containing double bonds and / or A2) a styrene-ethylene-ethylene / propylene-styrene block copolymer, B) a hydrogenated styrene block copolymer functionalized by grafting with an anhydride of an unsaturated organic acid or a vinyl alkoxysilane or a vinyl acyloxysilane or a methacryloxyalkylalkoxysilane or a methacryloxyalkylacyloxysilane, and C) hollow glass spheres. The invention also relates to a process for producing a thermoplastic elastomer using the thermoplastic elastomer composition and the thermoplastic elastomer obtained therein.
