Crosslinkable polysilane compositions and cured products thereof

摘要

Crosslinkable polysilane compositions contain (1) an alkenylsiloxy-terminated polysilane and a compound having at least three hydrosilyl groups in a molecule, (2) a hydro-siloxy-terminated polysilane and a compound having at least three alkenyl groups in a molecule, (3) a hydro-terminated polysilane and a compound having at least three alkenyl groups in a molecule, or (4) an alkenyl-terminated polysilane and a compound having at least three hydrosilyl groups in a molecule. By effecting hydrosilylation reaction between the components in the presence of a hydrosilylation catalyst, a tough crosslinked film is obtained without causing scission of a polysilane chain.
