Abstract
The invention is a method for the preparation of organic solvent-soluble polyheterosiloxanes containing MO.sub.2 (M=Ti or Zr) and SiO.sub.2 units. A compound MA.sub.4 (M=Ti or Zr, A=hydrolyzable group) and a compound Si(OR).sub.4 (R=hydrocarbon group or alkali metal atom) are hydrolyzed and condensed in the presence of a carboxylic acid, a phenol, or a diketone. This is followed by the addition of an organosilane R.sup.1.sub.3 SiX (R.sup.1 =hydrogen or hydrocarbon group, X=hydrolyzable group) and hydrolysis and condensation.
