ABSTRACT:
Disclosed is a method of producing dimethylpolysiloxanes through hydrolysis of dimethyldichlorosilane wherein a water solution containing a water-soluble oxygen-containing organic compound is introduced into dimethyldichlorosilane. Therein, linear dimethylpolysiloxanes alone having both ends blocked with chlorine atoms can be selectively produced by properly controlling the water content in the hydrolysis system and further by rendering the hydrolysis system acidic, and cyclic dimethylpolysiloxanes alone can also be selectively produced by properly controlling the water content in the hydrolysis system and optionally rendering the hydrolysis system acidic.
