Abstract
The present invention relates to a method of preparing a material formed from arborescent-branched molecules comprising associative groups that includes the following successive steps: (a) the reaction of at least one at least trifunctional compound (A) bearing first and second functional groups with at least one bifunctional compound (B), the functional groups of which are capable of reacting with the first functional groups of the compound (A); and (b) the reaction of the compound(s) obtained in step (a) with at least one compound (C) bearing, on the one hand, at least one reactive group capable of reacting with the second functional groups of (A) and, on the other hand, at least one given associative group.
