Abstract (en)
[origin: WO2013092809A2] The invention relates to a thermoreversibly cross-linked graft polymer, to the method for preparing same, and to the use of such a graft polymer in preparing a thermoreversibly cross-linked bitumen/polymer composition. The present invention also relates to a thermoreversibly cross-linked bitumen/polymer composition comprising such a graft polymer, to the method for preparing same, and to bituminous asphalt including such a composition. The polymer comprises: a main polymer chain P consisting of conjugated diene units; at least one side graft G having the following general formula (1): R-(OCH2CH2)m-S---, where R is a straight or branched saturated hydrocarbon chain having at least 18 carbon atoms, and m is an integer varying from 0 to 20, said graft G being connected to the main polymer chain P via the sulfur atom of formula (1); and at least one graft G' having the following general formula (4): ---S-R'-S---, where R' is a straight or branched, saturated or unsaturated hydrocarbon grouping having 2 to 40 carbon atoms, optionally including one or more heteroatoms, said graft G' being connected to the main polymer chain P via each sulfur atom of formula (4).
