Abstract:
Mixtures of cyclic branched siloxanes having exclusively D and T units, with the proviso that the cumulative proportion of the D and T units having Si-alkoxy and/or SiOH groups that are present in the siloxane matrix, determinable by  29 Si NMR spectroscopy, is greater than 2 and less than 10 mole per cent, are described, as are branched organomodified siloxanes obtainable therefrom.

Claim (Index 7):
The process for preparing mixtures of cyclic branched siloxanes having exclusively D and T units according to  claim 1 , comprising\n (a) an acid-catalysed equilibration of trialkoxysilanes with siloxane cycles and/or \u03b1,\u03c9-dihydroxypolydimethylsiloxane in the presence of at least one acidic catalyst and then (b) a hydrolysis and condensation reaction initiated by addition of water, and addition of a silicon-containing solvent, followed by (c) a distillative removal of the alcohol released, of water present in the system and of silicon-containing solvent, and a neutralization or removal of the acidic catalyst and optionally removal of salts that have possibly formed, wherein the silicon-containing solvent preferably comprises the isomeric siloxane cycles octamethylcyclotetrasiloxane (D 4 ), decamethylcyclotetrasiloxane (D 5 ) and/or mixtures thereof, advantageously working in mass ratios of silicon-containing solvent to the siloxane having D and T units of 1:1 to 5:1.
