Description

Изобретение относитс  к способу получени  аминоалкоксиполисилоксанов.The invention relates to a method for producing aminoalkoxypolysiloxanes.

Известен способ получени  аминоалкоксиполисилоксанов путем взаимодействи  в присутствии щелочного катализатора алкоксиорганополисилоксанов с аминоспиртами. Однако , нар ду с основной реакцией происходит расщепление полиорганосилоксанов.A known method for producing aminoalkoxypolysiloxanes by reacting, in the presence of an alkaline catalyst, alkoxyorganopolysiloxanes with amino alcohols. However, along with the main reaction, polyorganosiloxanes are split.

Получение аминоалкоксигидридполисилоксанов этим способом невозможно, так как происходит отщепление водорода.The preparation of aminoalkoxyhydride-polysiloxanes by this method is impossible, since hydrogen is removed.

С целью повыщени  выхода аминоалкоксиполисилоксанов и получени  аминоалкоксигидридполисилоксаиов , провод т взаимодействие алкоксиорганополисилоксанов с аминосодержащими силанами общей формулыIn order to increase the yield of aminoalkoxypolysiloxanes and to obtain aminoalkoxyhydridepolysiloxai, alkoxyorganoganopolysiloxanes are reacted with amino-containing silanes of the general formula
