FIELD: chemistry.
SUBSTANCE: disclosed is a method of producing polyorganosiloxanes by reacting α,ω-dihydroxy dialkyloligosiloxane with dialkyl-bis-(N,N-dialkylamino)silanes at room temperature in an atmosphere of an inert gas for 1-10 hours in the presence of an alkylamide of a carboxylic acid.
EFFECT: disclosed method of producing polyorganosiloxanes is characterised by easy implementation, availability of starting components and enables to obtain polyorganosiloxanes with different radicals at the silicon atom.
