Title
(EN) SILICON GLYCAN AND METHOD OF PREPARING SAME
(FR) GLYCANE DE SILICIUM ET SON PROCÉDÉ DE PRÉPARATION
Abstract
(EN)
A silicon glycan is provided. The silicon glycan comprises a glycoside moiety, independently selected organosilicon moieties, and beta-amino alcohol moieties joining the organosilicon moieties to the glycoside moiety. The glycoside moiety comprises independently selected saccharide moieties, which may be substituted with hydrocarbyl groups, ether moieties, and/or amine moieties. A method of preparing the silicon glycan is also provided. The method includes reacting (A) an aminoethyl polysaccharide and (B) an epoxide-functional organosilicon compound, to give the silicon glycan. The method may include preparing the aminoethyl polysaccharide (A) by first reacting (At) a hydroxyl- functional polysaccharide and (A2) an aziridinium halide compound to give the aminoethyl polysaccharide (A).

L'invention concerne un glycane de silicium. Le glycane de silicium comprend une fraction glycoside, des fractions d'organosilicium sélectionnées indépendamment, et des fractions de bêta-aminoalcool joignant les fractions d'organosilicium à la fraction glycoside. La fraction glycoside comprend des fractions saccharide sélectionnées indépendamment, lesquelles peuvent être substituées par des groupes hydrocarbyle, des fractions éther et/ou des fractions amine. L'invention concerne également un procédé de préparation du glycane de silicium. Le procédé consiste à faire réagir (A) un polysaccharide d'aminoéthyle et (B) un composé d'organosilicium à fonction époxyde, pour obtenir le glycane de silicium. Le procédé peut consister à préparer le polysaccharide d'aminoéthyle (A) en faisant d'abord réagir (A1) un polysaccharide à fonction hydroxyle et (A2) un composé d'halogénure d'aziridinium pour obtenir le polysaccharide d'aminoéthyle (A).
