Abstract: The invention relates to novel hybrid compounds comprising at least one polyon entity (Po)—for example oligomer or polymer—in which at least one of the hydroxyl functions of Po is substituted by at least one entity A that can be of a variable nature, for example polymer (e.g. polyorganosiloxane-POS), hydrocarbonated or mineral. The bond Ro between the entity Po and the entity A is obtained by means of “click chemistry” and corresponds to formula (II.1) or (II.2), Z representing —CH— or —N—. A is an entity selected from the group comprising the various polyols of Po, polyorganosiloxanes (POS), polyalkylene glycols, polyamides, polyesters, polystyrenes, alkyls, alkenyls, alkynyls, aryls, and combinations thereof, in addition to mineral materials such as silica and the combinations thereof. Said hybrid components can be used as emulsifiers, especially for cosmetics.

Abstract: The invention relates to novel hybrid compounds comprising at least one silicone entity (Sil) in which at least one of the silicons of Sil is substituted by at least one unit—Ro-B, B being an entity of a variable nature, for example polymer, hydrocarbonated or mineral, selected from a group comprising polyols (e.g. saccharides), silicones, polyalkylene glycols, polyamides, polyesters, polystyrenes, alkyls, alkenyls, alkynyls or aryls, in addition to mineral materials such as silica and the combinations thereof. The bond Ro between the entity Sil and the entity B is obtained by means of “click chemistry” and corresponds to formula (II.1) or (II.2), Z representing a carbon atom or a nitrogen atom. Said hybrid components can be used as emulsifiers, especially for cosmetics.

Abstract: Novel glycopolymers, uses thereof, and monomers useful for preparation thereof are provided. Methods for preparing novel monomers and glycopolymers are also provided. An exemplary polymer can include glycoside containing units and cationic or potentially cationic units.

Abstract: Disaccharides of formula (I) are derived from a-maltosyl fluoride, wherein R1 and R2 are defined. Such disaccharides are useful as glycosyl donors in transglycosylation reactions catalyzed by glycoside-hydrolazes or in transfer reactions catalyzed by transglycosylases during the preparation of oligosaccharides or polysaccharides.

Abstract: The invention concerns disaccharides of formula (I) derived from &agr;-maltosyl fluoride, wherein R1 and R 2 are such as defined in Claim 1. Said disaccharides are useful as glycosyl donors in transglycosylation reactions catalysed by glycoside-hydrolases or in transfer reactions catalysed by transglycosylases during the preparation of oligosaccharides or polysaccharides.
