10 Claims

1. A composition comprising a silylated polysaccharide, where the silylated polysaccharide is characterized by:

a. comprising linked fructose, galactose, anhydrogalactose, or glucose saccharide units provided that glycosidic linkages of glucose are alpha linkages and that the silylated polysaccharide is other than a silylated starch; and

b. on average 1 to 100 mole-percent of the hydroxyl groups on the polysaccharide have been silylated with a silyl group having the structure —SiR₃linked to the polysaccharide through a C—O—Si bond where each R is independently selected from hydrocarbyl radicals having from one to 12 carbon atoms, provided that on average at least one R per polysaccharide has a terminally unsaturated carbon-carbon double bond.
