摘要： A process for preparing a cyclic polysiloxazane is disclosed. The cyclic siloxazane may optionally be converted to an α-alkoxy-ω-amino-functional polysiloxane. The cyclic siloxazane or the α-alkoxy-ω-amino-functional polysiloxane, may be used as a capping agent for a silanol-functional polyorganosiloxane in a process to make an amino-functional polyorganosiloxane.

摘要： A method of making a polysilylether (PSE) polymer includes: cooling a solution of diethylamine to 0° C. under argon; adding cold dialkyldichlorosilane to form a first mixture; slowly warming the first mixture to form dialkylbis(diethylamino)silane; diluting the first mixture with hexane then filtering via cannula; evaporating the hexane and excess diethylamine; purifying the dialkylbis(diethylamino)silane under vacuum distillation; adding the dialkylbis(diethylamino)silane to a solution of diol dissolved in tetrahydrofuran to form a second mixture; heating the second mixture to 60° C. while reflux condensing, and cooling and concentrating the second mixture under vacuum to form a resultant mixture containing the polysilylether (PSE) polymer.

摘要： To provide a method for manufacturing a purified product of an alkyl-modified polydimethylsiloxane that is practically odorless and compatible with other cosmetic raw materials. The manufacturing method comprises the steps of: [A] synthesizing an alkyl-modified polydimethylsiloxane by subjecting a hydrosilyl-containing polydimethylsiloxane and an C2-C30 α-olefin to a hydrosilation reaction, and [B] subjecting the crude alkyl-modified polydimethylsiloxane obtained in Step [A] to a treatment of rendering it odorless by a hydrogenation reaction in the presence of a hydrogenation catalyst in an organic solvent (c) that is essentially free of active hydrogen atoms and has a boiling point equal to or greater than 70° C.

摘要： Provided are a polycarbonate-polyorganosiloxane copolymer having a carbon tetrachloride concentration of less than 4 ppm by mass, and the following production method for producing the polycarbonate-polyorganosiloxane copolymer. More specifically, provided is a method of continuously producing a polycarbonate-polyorganosiloxane copolymer, the method comprising the steps of: (A) continuously or intermittently taking a polymerization reaction liquid, which is obtained by polymerizing a dihydric phenol compound, a carbonate precursor, and a specific polyorganosiloxane in the presence of an alkaline compound aqueous solution and a water-insoluble organic solvent, out of a reactor; (B) separating the polymerization reaction liquid taken out in the step (A) into an aqueous phase and a water-insoluble organic solvent phase; (C) washing the water-insoluble organic solvent phase separated in the step (B), followed by separation thereof into an aqueous phase and a water-insoluble organic solvent phase; (D) concentrating the water-insoluble organic solvent phase separated in the step (C); and (E) recovering part or all of the water-insoluble organic solvent removed by evaporation in the step (D), followed by distillation purification thereof in a distillation column, the water-insoluble organic solvent obtained in the step (E) being reused as at least part of the water-insoluble organic solvent in the step (A) or as an extraction solvent for the aqueous phase separated in the step (B), or as both thereof, in the step (E), the distillation purification being performed while a concentration of the polycarbonate-polyorganosiloxane copolymer in a column bottom liquid of the distillation column is controlled to 6% by mass or less.

摘要： A method for purifying a reclaimed polymer, such as a polymer reclaimed from post-consumer use or post-industrial use, is disclosed. The method involves obtaining the reclaimed polymer and contacting it at an elevated temperature and pressure with a fluid solvent to produce an extracted reclaimed polymer. The extracted reclaimed polymer is dissolved in a solvent at an elevated temperature and pressure to produce a polymer solution. A polymer is then separated from the polymer solution.

The solid material or oily material that is obtained is dissolved in an organic solvent, and a substrate is brought into contact with a solution that is obtained to form a highly functional organic thin film on the substrate.[Chemical Formula 1] R1nMXm−n  (I)
