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 presenc? of a 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.
