1. Method for producing functionalised telechelic oligomers, comprising:
a) bringing a raw material consisting of at least one high-molecular-weight polymer comprising at least two unsaturations, into contact with a solution comprising at least one ionic liquid, at least one metathesis catalyst and at least one functionalising agent chosen from hydrogenocarbonated molecules having a symmetrical disubstituted carbon-carbon double bond and two functions chosen from a group comprising ketone, aldehyde, ester, amine, amide, imine, alcohol, ether, nitrile, thioether, thioketone, thioester, sulphoxide, phosphine, nitro, imidazole, and quaternary ammonium and in this latter case the anion is chosen from a group comprising fluoride, chloride, bromide, iodide, tosylate, and triflate; and b) the separation of the functionalised telechelic oligomers produced by the metathesis reaction in an ionic liquid medium of the step a). |
