Abstract: The invention relates to a method for preparing compositions having a high degree of elasticity under suddenly applied stress by mixing a composition containing diorganopolysiloxanes in which a few siloxane units or silanes are present which have a functionality higher than the functionality of the diorganopolysiloxane units with a condensation catalyst obtained from the reaction of dialkyldialkoxysilanes and tin carboxylates.
