<p>Polyether-quaternized-functional polysiloxanes comprising a polysiloxane structure with terminal polyether residues and terminal amino groups quaternized with anions of a physiologically harmless acid. Polyether-quaternized-functional polysiloxanes of formula (I), a = 5-500; b = 0-50; c = 0-20; R<1> = 1-8C aliphatic or aromatic hydrocarbyl; R<2> = R<2>A or R<2>B, with at least one of each on the siloxane structure; R<2>A = a polyether group of formula -(Y)(O(C2H4-dR<3>dO)e(CfH2fO)gX)n (II); Y = an (n+1)-valent, optionally branched hydrocarbon residue; d = 1-3; e, g = 1-20; f = 2-4; n = 1-4; X = H, 1-10C hydrocarbyl or 1-10C acyl; R<2>B = a group -M-Z; Z = -N<+>R<4>R<5>R<6> A<->, -N<+>R<4>R<6>-(CH2)e-R<7>-CO-R<4> A<->, -N<+>R<4>R<5->R8-NR<4>R<5> A<->, -N<+>R<4>R<6>-(CH2)e-NR<4>R<5> A<-> or -N<+)<C2H4OH)2-(CH2)eCH3 A<->; R<3>-R<6> = H or 1-2C alkyl; R<7> = -O- or -NR<9>-; R<8> = as for Y; R<9> = H or 1-6C alkyl; A = inorganic or organic anions of physiologically harmless acids HA; M = a divalent group selected from -(CH2)3OCH2CH(OH)CH2-, -(CH2)2-Cyc-, -(CH2)3OCH2CH(CH2OH)CH2-, -(CH2)xCH2CH(OH)CH2-, -(CH2)xCH2CH(CH2OH)- or -Nor-; Cyc = 1,3-cyclohexylene substituted with hydroxyl at position 4 or 1,4-cyclohexylene substituted with OH at position 3; Nor = 6,2-norbornylene substituted with OH at position 3 or 6,3-norbornylene substituted with OH at position 2.</p> |
