METHOD OF PRODUCING PLATINUM-ALKENYL-POLYSILOXANE COMPLEX, PLATINUM-ALKENYL-POLYSILOXANE OBTAINED THROUGH THE METHOD AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a novel method of producing almost colorless platinum- alkenylpolysiloxane complex having no defect of prior arts. SOLUTION: As platinum is charged as an autocatalyst in the form of platinum complex and at least one of base is charged in an oxidative organic solvent/mixed solvent relating to platinum halide, a platinum halide is allowed to react with at least one of alkenylpolysiloxane, activated carbon concentrated suspension is admixed to the reaction mixture. Subsequently, the solid particles and activated carbon are separated from the first liquid phase or the solid particles and activated carbon are separated from the liquid phase and the liquid phase is continuously concentrated and admixed.
