Fatty acid polyester derivatives of polyglycosides formed from a polyol having between 2 and 10 hydroxy functions, the 2 hydroxy functions or at least 2 of these hydroxy functions being bound to the anomeric carbon of a reducing carbohydrate that is identical or different for each hydroxy group and selected from the monosaccharides and disaccharides, in which at least one of the other hydroxy groups of the monosaccharide or the disaccharide is esterified by a lipid derivative bearing at least one double bond optionally originating from a vegetable or animal oil, from a mixture of vegetable or animal oils, the double bond or the at least one of the double bonds of the lipid derivative being functionalized by a group selected from the epoxy, amine, alcohol and acid groups, and use thereof in particular in reaction formulations for the production of polymer materials.

Fatty acid polyester derivatives of polyglycosides

The present invention relates to a cross-linkable composition comprising: i) a fluorinated &#x3b1;,&#x3c9;-bis(propargyl) oligomer of formula (I): in which m is 1 to 100, e.g. 1 to 93, n is 2 to 150, e.g. 1 to 128, p is 0 to 2, preferably 0 or 1.75, and n, m and p are selected such that the fluorinated &#x3b1;,&#x3c9;-bis(propargyl) oligomer of formula (I) has a number average molar mass Mn of 400 to 25000; ii) a cross-linking agent comprising at least three azide-Ngroups; and iii) optionally, a fluorinated oligomer comprising two terminal azide-N3 or fluorinated &#x3b1;,&#x3c9;-bis(azide) oligomer groups. The invention also relates to a material comprising the click chemistry reaction product of the cross-linkable composition of the invention, to a method for preparing said material and to the uses thereof.
