Claim:
An ionically-modified saccharide siloxane copolymer, comprising the reaction product of a saccharide-siloxane copolymer and an ionic monomer or oligomer, said saccharide-siloxane copolymer comprising a saccharide component and an organosiloxane component which are linked by a linking group having the formula: R 2 a R 1 (3−a) SiO—[(SiR 2 R 1 O) m —(SiR 1 2 O) n ] y —SiR 1 (3−a) R 2 a wherein each R 1 can be the same or different and comprises hydrogen, C 1 -C 12 alkyl, an organic radical, or R 3 -Q, Q comprises an epoxy, cycloepoxy, primary or secondary amino, ethylenediamine, carboxy, halogen, vinyl, allyl, anhydride, or mercapto functionality, m and n are integers from 0 to 10,000 and may be the same or different, each a is independently 0, 1, 2, or 3, y is an integer such that the copolymer has a molecular weight less than 1 million, R 2 has the formula Z-(G 1 ) b -(G 2 ) c , and there is at least one R 2 per copolymer, wherein G 1 is a saccharide component comprising 5 to 12 carbons, b+c is 1-10, b or c can be 0, G 2 is a saccharide component comprising 5 to 12 carbons additionally substituted with organic or organosilicon radicals, Z is the linking group and is independently selected from the group consisting of: —R 3 —NHC(O)—R 4 —; —R 3 —NHC(O)O—R 4 —; —R 3 —NH—C(O)—NH—R 4 —; —R 3 —C(O)—O—R 4 —; —R 3 —O—R 4 —; —R 3 —CH(OH)—CH 2 —O—R 4 —; —R 3 —S—R 4 ; —R 3 —CH(OH)—CH 2 —NH—R 4 —; —R 3 —N(R 1 )—R 4 ; and R 3 and R 4 are divalent spacer groups comprising (R 5 ) r (R 6 ) s (R 7 ) t , where at least one of r, s and t must be 1, and R 5 and R 7 are either C 1 -C 12 alkyl or ((C 1 -C 12 )O) p where p is any integer 1-50 and each (C 1 -C 12 )O may be the same or different, R 6 is —N(R 8 )—, where R 8 is H or C 1 -C 12 alkyl, or is Z-X where Z is previously defined or R 3 , X is a carboxylic acid, phosphate, sulfate, sulfonate or quaternary ammonium radical, and at least one of R 3 and R 4 must be present in the linking group and may be the same or different, and wherein the saccharide-siloxane copolymer is a reaction product of a functionalized organosiloxane polymer and at least one hydroxy-functional saccharide such that the organosiloxane component is covalently linked via the linking group, Z, to the saccharide component.
