摘要： A method for preparing a siloxane-(meth)acrylate macromonomer is provided. The method includes hydrosilylation, hydrolysis, and condensation. By-products of the method may be recycled to produce additional siloxane-(meth) acrylate macromonomer. An exemplary siloxane-(meth)acrylate macromonomer prepared by the method is 3-(1,1,1,3,5,5,5-heptamethyltrisiloxan-3-yl)propyl methacrylate.

摘要： A method for preparing a silyl ester compound is disclosed. The silyl ester compound may be a silane monomer or siloxane oligomer. The silyl ester compound may be hydro silylated with a polyorganohydrogensiloxane to form a silyl ester protected product, which may then be de-protected with water to prepare a carboxy-functional polyorganosiloxane.

摘要： A method for preparing functionalized polyorganosiloxanes is disclosed. The method includes 1) combining starting materials including A) a boron-containing Lewis acid catalyst, and B) an organosilicon compound having an average, per molecule of at least 1 silicon bonded groups of the formula —OR2; wherein each R2 is an independently selected monovalent hydrocarbon group of 1 to 6 carbon atoms, thereby forming a catalyzed mixture; and thereafter 2) adding the catalyzed mixture into a starting material including C) an organohydrogensiloxane having at least 1 silicon bonded hydrogen atom per molecule, thereby preparing a product comprising the functionalized polyorganosiloxane and a by-product comprising HR2.

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.
