Title: Hydrosilylation crosslinking of thermoplastic elastomer

Abstract: In the preparation of thermoplastic elastomers by hydrosilylation crosslinking of the elastomeric component, the use of an elastomer containing a non-conjugated diene and having a Mooney viscosity within the MST range of 45 to 100 provides products with a high level of crosslinking and an improved combination of physical properties. This improvement is obtained even at low concentrations of hydrosilylation catalyst.
