Patent ID: 7649087

Claim:
A saccharide residue-functional organopolycarbosiloxane having the formula: {XR 1 a SiO (3−a)/2 } x {R 1 b SiO (4−b)/2 } y wherein R 1 is C 1 to C 10 alkyl or aryl; a is an integer from 0 to 2; b is an integer from 0 to 3; x is an integer with a value of at least 2; y is an integer with a value of at least 0; and X is a silylalkyl group having the formula at i=1: wherein R 1 is C 1 to C 10 alkyl or aryl, R 2 is C 2 to C 10 alkylene, R 3 is C 1 to C 10 alkyl, i represents an iteration or generation number and is an integer from 1 to 10, b i is an integer from 0 to 3, c i is an integer from 0 to 3, the sum of b i and c i is less than or equal to 3, and X i+1 at the point at which i corresponds to the iteration or generation number for the silylalkyl group X is a group with the general formula —R 4 S—R 5 Y wherein R 4 and R 5 are each independently selected from C 1 to C 20 divalent hydrocarbyl, and Y is selected from the group consisting of a substituted monosaccharide, substituted polysaccharide, unsubstituted monosaccharide and unsubstituted polysaccharide residues having an oxygen atom bonded to R 5 ; provided the organopolycarbosiloxane contains at least two saccharide groups per molecule.
