Summary:A method for preparing a silicon glycan is provided. The method includes reacting (A) a polysaccharide and (B) an anhydride-functional organosilicon compound, to give the silicon glycan. The silicon glycan comprises a glycoside moiety, independently selected organosilicon moieties, and linking moieties joining the organosilicon moieties to the glycoside moiety. The glycoside moiety comprises independently selected saccharide moieties, which may be substituted with substituted or unsubstituted hydrocarbyl groups, ether moieties, and/or amine moieties. L'invention concerne un procédé de préparation d'un glycane de silicium. Le procédé consiste à faire réagir (A) un polysaccharide et (B) un composé d'organosilicium à fonction anhydride, pour obtenir le glycane de silicium. Le glycane de silicium comprend une fraction glycoside, des fractions d'organosilicium sélectionnées indépendamment, et des fractions de liaison joignant les fractions d'organosilicium à la fraction glycoside. La fraction glycoside comprend des fractions saccharide sélectionnées indépendamment, lesquelles peuvent être substituées ou non par des groupes hydrocarbyle, des fractions éther et/ou des fractions amine.
