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.

Thermoplastic A thermoplastic elastomer, comprising a structurally modified hydrophilic or hydrophobic fumed silica.
A process for improving mechanical properties of a thermoplastic elastomer, the process comprising adding a hydrophilic or hydrophobic fumed silica, which has been structurally modified, to the thermoplastic elastomer.
A process for improving tear resistance of a thermoplastic elastomer, the process comprising adding a hydrophilic or hydrophobic fumed silica, which has been structurally modified, to the thermoplastic elastomer.
