Abstract
This invention relates to a method for producing functionalized telechelic oligomers, comprising two steps. The first step relates to bringing a raw material comprising at least one high-molecular-weight polymer comprising at least two unsaturations, into contact with a solution comprising at least one metathesis catalyst and at least one functionalizing agent. The second step relates to the separation of the functionalized telechelic oligomers produced by the metathesis reaction in ionic liquid medium of the first step.
