This invention relates to a process for preparation of non--crosslinked linear monofunctional and telechelic difunctional unsaturated polymers wherein the functional groups are reactive terminal groups other than vinyl groups. The average functionality number of the monofunctional unsaturated polymers is at least 0.7, as determined by nuclear magnetic resonance spectroscopy (NMR). The average functionality number of the telechelic difunctional polymers is at least 1.6- 1.7, as determined by NMR. Monofunctional olefins and difunctional olefins are reacted with cyclic olefins or unsaturated polymers to prepare difunctional polymers. The process is substantially free of side reactions comprising double bond migration and cyclization. The unsaturated functional polymers can be reacted in condensation, addition and transesterification reactions to prepare polyesters, graft copolymers, polyurethanes, polyureas, polyamides, thermoplastic and thermosetting resins, block copolymers, ion exchange resins, adhesives, films, fibers, foams and flocculants.
