Abstract (en)
[origin: WO2011135550A1] The invention relates to the use in a bituminous composition of an organogelator molecule of the following general formula (I): X- -R, (Y)n ¦(R2)c o, where: A is a hydrocarbon group which can be straight or branched, saturated or unsaturated, acyclic, cyclic or polycyclic, having 3 to 92 carbon atoms, resulting from the polymerisation of lateral chains of at least one unsaturated fatty acid; X is an NH group or an oxygen atom O; Ri is a group selected from: a straight or branched hydrocarbon group having 2 to 40 carbon atoms, optionally including one or more heteroatoms and optionally including one or more unsaturations, or an aromatic group, substituted or otherwise; R2 is a group selected among: a hydrogen atom, a straight or branched hydrocarbon group having 1 to 40 carbon atoms, including one or more heteroatoms and optionally including one or more unsaturations, or an aromatic group, saturated or otherwise; m and n are, separately from one another, an integer ranging from 1 to 4; p is an integer ranging from 0 to 4; q is an integer ranging from 1 to 4 or a combination of said values; Y is a group including a hydrogen bond donor such as the NH grouping and a hydrogen bond acceptor such as the C=O grouping, to improve the resistance thereof to aggressive chemical agents, in particular to hydrocarbons such as gasolines, diesels and/or kerosenes.
