ABSTRACT:
Polymers of olefins such as ethylene and propylene, having functional groups introduced into both the ends thereof, can be provided which are useful as macromonomers for polycondensation. This new polymer comprises a recurring unit represented by the general formula --(--CH.sub.2.CHR--)-- and having functional groups bonded to both the ends of the polymer and a number average molecular weight of 300 to 500,000, the functional groups being selected from the group consisting of H.sub.2 C.dbd.CH-- group and ##STR1## wherein X is --OH, --OR.sup.1, a halogen atom or --SO.sub.3 R.sup.2, R.sup.1 is a hydrocarbon group of 1 to 5 carbon atoms and R.sup.2 is a halogen-substituted or non-substituted hydrocarbon group of 1 to 20 carbon atoms.
