Hydrosilylation crosslinking

摘要

An improved process for the preparation of thermoplastic elastomers by hydrosilylation crosslinking, in which a very low amount of a platinum containing hydrosilylation catalyst is used in combination with specific diene containing rubbers. In another variant of the invention, the hydrosilylation is carried out in the presence of process oil which is substantially free of materials having the chemical behavior of a Lewis base. A crosslinked rubber component is obtained in the thermoplastic elastomer composition.
