<p>Disclosed is a method for the preparation of high molecular-weight silicone resins that have excellent storage stability in solution form. The method comprises the hydrolysis and condensation of a disiloxane and an alkyl silicate in an aqueous solution which contains at least 30 weight% alcohol and at least 5 weight% inorganic acid followed by isolation of the resin with an organic solvent which is poorly soluble in water and which has a dielectric constant of at least 4.</p>
