    摘要： The present invention relates to a graft polymer PG including a polymer backbone P and at least one side graft G linked to the polymer backbone, the graft G having the general formula (1): in which R
    1 and R
    2 represent, separately from one another, straight or branched, unsaturated or saturated hydrocarbon groups, such that the total number of carbon atoms in groups R
    1 and R
    2 is between 2 and 110; X represents an amide, amino-acid, urea or urethane function, said graft G being linked to said polymer backbone P via the sulphur atom. The graft polymer PG is a polymer that allows thermoreversible cross-linking. The graft polymer PG can be used in many fields such as coatings, paints, thermoplastics, adhesives, lubricants, fuels, inks, cements, construction materials, rubbers and bitumens. The graft polymer PG can be used in particular for thermoreversibly cross-linking bitumen/polymer compositions and thus for reducing coating, spreading and/or compaction temperatures during the production of bituminous coated materials.

    摘要： Polymer network composition comprising a semi-crystalline covalently crosslinked polymer network including exchangeable covalent bonds and crosslinking bonds and at least an exchange reaction catalyst, wherein the number of crosslinking bonds is sufficient for the polymer network to be beyond the gel point and the number of exchangeable bonds is sufficient for the network to relax stresses and/or flow when conditioned at an appropriate temperature. Such compositions are characterized by the fact that the network is able to reorganize by exchange reactions that allow it to relax stresses and/or flow while maintaining network connectivity.
