The disclosure relates to a bitumen/polymer composition comprising at least one bitumen and at least one graft polymer, the grafts enabling the bitumen/polymer compositions to be thermoreversibly cross-linked. The disclosure also relates to the use of said bitumen/polymer compositions in fields of application relating to roads, especially in the production of asphalt binders, and in industrial fields of application. The disclosure further relates to the method for producing said thermoreversibly cross-linked bitumen/polymer compositions.

Graft polymer and thermoreversibly cross-linked bitumen composition comprising said graft polymer

The present invention relates to a method for synthesizing a supramolecular material comprising: 1&#x2014;the reaction of at least one carboxylic diacid, or ester or chloride of such a diacid, with, on the one hand, at least one modifier compound bearing both reactive functional groups capable of reacting with the carboxylic acid, ester or acid chloride functional groups and associative groups capable of associating with one another by hydrogen bonds, in a molar ratio of the reactive functional groups to the carboxylic acid, ester or acid chloride functional groups of between 0.10 and 0.50, and, on the other hand, at least one polyamine, said reactions being carried out successively or simultaneously, and 2&#x2014;the reaction of the polyamide obtained at the end of step 1 with urea. The present invention also relates to the resulting material, and also to the uses thereof.
