ABSTRACT:
Progress for preparing a catalyst for hydrosilylation reactions which comprises reacting (A) a rhodium complex Rh(R.sub.2 S).sub.3 X.sub.3, in which R represents alkyl and other specified hydrocarbon groups and X represents Cl or Br with (B) an organohydrogen polysiloxane in the presence of (C) an organosiloxane having silicon-bonded vinyl or allyl groups. The ratio of silicon-bonded hydrogen atoms provided by (B) to each Rh atom provided by (B) is in the range from 0.5:1 to 6.0:1.
The invention also includes the use of the catalyst for reacting .tbd.SiH with .tbd.Si Alkenyl especially in compositions for the treatment of substrates such as paper and plastics.
