1 represented by the above general formula according to the present invention,
1,1-trimethyl-3-hydrocarbyl-
3,3-Diacylaminodisiloxane can be used as a base agent in the same way as conventionally known polyfunctional amoxisilanes or siloxane compounds (see, for example, US Pat. No. 2,876,234, US Pat. No. 3,488,371, or US Pat. A cured composition can be obtained by adding it to a diorganopolysiloxane whose molecular chain ends are blocked with hydroxyl groups. That is, this compound has an extremely excellent chain lengthening effect on diorganopolysiloxanes whose molecular chain ends are blocked with hydroxyl groups.

On the other hand, most conventional diacetamidosilanes and siloxanes use difunctional silanes (dichlorosilanes) as starting materials;
Since the disiloxane according to the present invention uses relatively inexpensive trifunctional silane (trichlorosilane) as a starting material, the desired product can be obtained at low cost, and is therefore industrially advantageous.

After the dropwise addition was completed, the contents were stirred for 30 minutes, and then 90 g (1 mol) of trimethylsilanol was added dropwise over 30 minutes.Then, the temperature was raised to 60°C and stirred at the same temperature for 2 hours to complete the reaction. . After cooling to room temperature, the by-produced triethylamine hydrochloride was filtered out, the filtrate was stripped under reduced pressure to remove toluene, and the residual liquid was distilled under reduced pressure, resulting in a boiling point of 102°C/1.5
160 g of a liquid with a temperature of mmHg was obtained. This is the formula from the analysis result below. It was confirmed that it was a disiloxane shown by (yield 53%).
