ABSTRACT:
A method for maintaining catalytic activity during a hydrosilylation reaction between a silicon hydride and an unsaturated compound is disclosed. The method comprises reacting a silicon hydride and an unsaturated compound in the presence of a platinum catalyst wherein a peroxide is added into the reaction mixture to maintain the catalytic activity of the platinum catalyst.
