摘要：<p>The invention provides a method for the preparation of a solvent-borne silicone resin containing polymetallosiloxane, wherein a metal containing material is hydrolysed and condensed with a silicon containing reactant in a solvent that the polymetallosiloxane and the silicon containing reactant at least are soluble in. The metal is chosen from Transition Group metals, IIIA Group element, Zr or Sn, and the metal containing material is preferably at least one boron containing material selected from boric acid or an of its salts, boron anhydride, boronic acid, alkoxyborate or a mixture thereof. The silicon containing reactant is preferably an alkoxysilane, hydroxysilan, alkoxysiloxane or hydroxysiloxane, and the solvent is an organic solvent. The solvent-borne silicone resin itself is claimed as well as its use in a thermoplastic or thermosetting organic polymer or rubbers or blends thereof in the enhancement of the scratch and/or abrasion resistance of the composition or coating.</p>
