Abstract

Thermoplastic elastomer, which comprises a fumed, hydrophilic or hydrophobic silica, which has been structurally modified and also a process for the improvement of the mechanical properties of thermoplastic elastomers. The thermoplastic elastomers are produced by preparing a masterbatch from the components (e.g. thermoplastic resin component and fumed silica) and compounding this with further thermoplastic elastomers.
