Abstract
A thermoreversibly cross-linked graft polymer, which may be used in bituminous asphalt, includes: 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, the 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 linear or branched, saturated or unsaturated hydrocarbon grouping having from 2 to 40 carbon atoms, optionally including one or more heteroatoms, the graft G′ being connected to the main polymer chain P via each sulfur atom of formula (4).
