  • Process For Preparing Graft Polymers Without Initiator And Without Solvent And Bitumen/Polymer Compositions Comprising Said Graft Polymers
    Publication number: 20150094405
    Abstract: A process for preparing graft polymers from a polymer is based on conjugated diene units and a graft which is a thiol derivative. The process has an absence of solvent and any radical initiator. The graft polymer can be advantageously be used as additive for a bitumen/polymer composition and in particular permits thermoreversible cross-linking.
    Type: Application
    Filed: October 10, 2014
    Publication date: April 2, 2015
    Applicants: TOTAL RAFFINAGE MARKETING, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS)-
    Inventors: Sylvia Harders, Romuald BOTEL, Ilias ILIOPOULOS, Ludwik LEIBLER, Ornella Annabelle ZOVI

  • GRAFT POLYMER, AND THERMOREVERSIBLY CROSS-LINKED BITUMEN/POLYMER COMPOSITION CONTAINING SUCH A GRAFT POLYMER
    Publication number: 20140329939
    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).
