成果简介	NOVELTY - Invention relates to chemical engineering of high-molecular organosilicon compounds. Disclosed is a method of processing linear, branched, cross-linked high-molecular polyorganosiloxanes and cross-linked filled silicones based thereon to cyclic and linear structure diorganosiloxanes, which involves reaction of polyorganosiloxanes of general formula (I), where R1 and R2 independently denote H, CH3, C2H5, C3H8, C4H9, C2H3, C3H5, C6H5; R3 denotes H, CH3, C2H5, C3H8, C4H9, C2H3, C3H5, C6H5, OH, with water in liquid ammonia medium in autoclave at 100–200 °C. Method makes it possible to control composition of obtained mixture of diorganosiloxanes depending on conditions and reuse spent ammonia without additional purification procedures. USE - Chemistry. ADVANTAGE - Universal technological method which provides processing of filled silicone wastes of various types to diorganosiloxanes of cyclic and linear structure and does not require use of organic solvents and catalysts. 1 cl, 1 tbl, 8 ex
