A process is disclosed for preparation of telechelic difunctional unsaturated oligomers and polymers having at least one internal carbon-to-carbon double bond wherein the functional groups are terminal reactive groups. The reactants are acyclic polyenes with terminal carbon-to-carbon double bonds and olefins with at least one functional group. The polymerization process is substantially free of side reactions comprising double bond migration and cyclization. The telechelic difunctional unsaturated oligomers and polymers have a functionality of about 2 and are suitable for preparation of block copolymers, ion exchange resins, adhesives, and flocculants and for further functionalization.
