Patent ID: 7732511

Claim:
Anhydrous bituminous products, characterized in that they contain one or more additives selected from: (A) the product resulting from the reaction of (di)alk(en)yl phenols on aldeydes, the aldehydes having from 1 to 10 carbon atoms, followed by a (poly)oxyethylation and/or (poly)oxypropylation, the alk(en)yl groups having between 1 and 50 carbon atoms, and able to be identical or different in the case of dialk(en)yl phenols, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molar mass of not less than 45 g/mol and not more than 20,000 g/mol, the number of phenolic units of product A varying between 3 and 50; (B) a (poly)oxyethylated and/or (poly)oxypropylated 2,2-bis(4-hydroxyphenyl)propane/epichlorohydrin copolymer, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molar mass of not less than 45 g/mol and not more than 20,000 g/mol; (C) a (poly)oxyethylated and/or (poly)oxypropylated bis(4-hydroxypheny)ethane/epichlorohydrin copolymer, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molar mass of not less than 45 g/mol and not more than 20,000 g/mol; (D) a (poly)oxyethylated and/or (poly)oxypropylated bis(4-hydroxyphenyl)methane/epichlorohydrin copolymer, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molar mass of not less than 45 g/mol and not more than 20,000 g/mol; (E) the product resulting from the (poly)oxyethylation and/or (poly)oxypropylation of an alkyldicarboxylic acid or mixture of alkyldicarboxylic acids, the alkyl groups having between 1 and 20, all the parts formed by (poly)oxyethylation and/or (poly)oxypropylation having a molar mass of not less than 100 g/mol and not more than 20,000 g/mol; (F) the product resulting from the (poly)oxyethylation and/or (poly)oxypropylation of a fatty acid, the number of carbon atoms of which is between 10 and 30, the part formed by (poly)oxyethylation and/or (poly)oxypropylation having a molar mass of not less than 100 g/mol and not more than 20,000 g/mol; (G) the product resulting from the reaction between product A and the mixture of products E and F; (H) a salt obtained from an alk(en)yl(aryl)sulphonic acid and an alk(en)yl(aryl)amine, the alk(en)yl(aryl) units having a number of carbon atoms between 6 and 30; or (I) a salt formed from an alk(en)yl(aryl)sulphonic acid and morpholine or pyrazine or pyrazoline or pyrazolone or pyridine or pyridone or pyrimidine or pyrrole or pyrrolidine or pyrrolidone or pyrroline or toluidine or imidazole or indol or indoline or oxindole, the alk(en)yl(aryl) units having a number of carbon atoms of between 6 and 30.
