manufacturing method for platinum alkenylpolysiloxan complexes, in particular platinum divinyltetramethyldisoloxan

摘要

Platinum-alkenylpolysiloxanes or platinum-divinyltetramethyldisiloxanes are prepared by reaction of a haloplatinum compound with at least one alkenylpolysiloxane by addition of platinum in the form of a platinum complex as an autocatalyst in the presence of at least one base in an organic solvent mixture that is oxidizable by the haloplatinum compound.
