    • An aminated polymer having excellent adhesion, printability, and compatibility in polymer blends or the like which are obtained by introducing an amino group, into an isotactic .alpha.-olefin polymer having an olefinic unsaturated bond at its terminus is disclosed. The terminal unsaturated isotactic or syndiotactic .alpha.-olefin polymer is obtained by polymerizing an .alpha.-olefin with a catalyst comprising the combination of a metallocene compound and an alumoxane, and the amino group is obtained by the amination of the terminal unsaturated group, by the addition of a compound containing the corresponding functional group to the unsaturated bond, or by the conversion of a precursor polymer containing a precursor of the functional group into a polymer containing the functional group desired.
