Title (EN) EMULSIONS OF BRANCHED ORGANOPOLYSILOXANES
(FR) ÉMULSIONS D'ORGANOPOLYSILOXANES RAMIFIÉS
Abstract: front page image
(EN)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.
(FR)L'invention concerne des organopolysiloxanes ramifiés, ainsi que des émulsions de ceux-ci, et des procédés de préparation et les utilisations de ces organopolysiloxanes ramifiés et des émulsions de ceux-ci. Un organopolysiloxane ramifié est préparé par la réaction d'un agent de ramification avec un organopolysiloxane sensiblement linéaire contenant au moins un groupe hydroxyle ou hydrolysable lié au silicium, en présence d'un fluide inerte et d'un catalyseur, tel qu'un catalyseur phosphazène. Les catalyseurs phosphazènes ont également l'avantage que la teneur en silicones cycliques de faible masse moléculaire non souhaités dans le produit de polymérisation est faible.
