  • Publication number: 20170174886
    Abstract: The invention relates to branched organopolysiloxanes and emulsions thereof, and to methods of preparation and uses of the branched organopolysiloxanes and emulsions thereof. A branched organopolysiloxane is prepared by the reaction of a branching agent with a substantially linear organopolysiloxane containing at least one hydroxyl or hydrolysable group bonded to silicon, in the presence of an inert fluid and a catalyst, such as a phosphazene catalyst. Phosphazene catalysts also have the advantage that the content of undesired low molecular weight cyclic silicones in the polymerisation product is low.
