Aqueous functional fluoroalkylgroup containing organopolysiloxane compositions, process for their preparation and their use

摘要

Water-based, organopolysiloxane-containing compositions, which are largely free from organic solvent, show a flash point of above 70 degrees C and do not release alcohol when diluted with water. These compositions contain polysiloxanes of formula HOÄSi(A)(CH3)z(OH)1-zOÜaÄSi(B)(R<2>)y(OH)1-yOÜbÄSi(C)(CH3< /SB>)OÜcÄSi(D)(OH)OÜdH . (HX)e (I), where A = amino-alkyl group derived from formula H2N(CH2)f(NH)g(CH2)hSi(OR)3-z(CH3)z (II); R = linear, branched or cyclic 1-8C alkyl, or aryl; f = 0-6; g = 0 if f = 0, or g = 1 if f = more than 0; h = 0-6; z = 0-1; B = fluoroalkyl group derived from formula R<1>-Y-(CH2)2Si(R<2>)y(OR)3-y (III); R<1> = mono-, oligo- or per- fluorinated 1-9C alkyl or aryl; Y = CH2, O or S; R<2> = as for R; y = 0-1; C = alkyl group derived from formula R<3>-Si(CH3)(OR)2 (IV); D = alkyl group derived from R<3>-Si(OR)3 (V); R<3> = linear, branched or cyclic 1-8C alkyl; X = residue of (in)organic acid; a, b = more than 0; c, d, e = 0 or more; and a+b+c+d = at least 2. Also claimed is a process for the production of these compositions.
