| titleOfInvention | Method of preparing polyorganosiloxane with functional groups in the presence of lithium silanolate |
| abstract | The invention relates to a method of preparing polyorganosiloxane containing at least one functional group in the structure thereof. The inventive method consists in reacting a polyorganosiloxane containing at least one hydroxyl group in the structure thereof with, using a silanol motif, at least one mole of a polyalkoxysilane having formula (R<1>)a(R<2>)bSi (OR<3>)4-(a+b) (I). R<1> represents an alkyl radical, a cycloalkyl radical, an aryl radical. R<2 >represents a group -(Z)m-(X)n, wherein m = 0 or 1, n = 1 or 2, Z represents a divalent hydrocarbon residue, X represents an unsaturated hydrocarbon radical when m = 0 and, when m = 1, X represents a residue selected from those having formula: atom of chlorine, bromine or iodine, -O-CO-CR<4>=CR<5>R<6> (in which R<4>, R<5> and R<6> each represent a hydrogen atom, an alkyl radical and/or a phenyl radical), -R<F> (in which R<F >represents a perfluorinated residue), -NHR<7> (in which R<7> represents a hydrogen atom, an alkyl radical, a radical -R<8>-NH2, wherein R<8> represents Z), -SH. R<3> represents an alkyl radical. Moreover, a = 0, 1, 2 or 3, b = 0 or 1 and a+b = 0, 1, 2 or 3, with the additional condition that the sum a+b = 3, symbol b cannot be equal to 0. The aforementioned method is performed in the presence of an effective quantity of a catalyst based on a derivative of lithium and is characterised in that: (i) the catalyst is a lithium organosilanolate having formula (R<1>)a(R<2>)b(OR<3>)3-(a+b)SiO<->Li<+> (II), wherein R<1>, R<2>, R<3>, a and b have the meanings indicated above; and (ii) the method is conducted in the absence of an aliphatic alcohol having formula R<3>OH which is added to the reaction medium. |
