    Abstract: A polymer composition containing:(a) at least one hydrophobic polymer, (b) at least one polyisobutene terminally modified with polar groups, obtainable by functionalization of reactive polyisobutene of number average molecular weight Mn = 150-50000 is new. Independent claims are also included for the following: (1) fibers, films, and shaped bodies built up from the polymer composition; (2) a process for preparation of the polymer composition by contacting the hydrophobic polymer (component A) or the monomer for preparation of this polymer with at least one polyisobutene (component B) modified with terminal polar groups; (3) a colored polymer composition containing:(a) at least one hydrophobic polymer as component A, (b) at least one polyisobutene terminally modified with polar groups obtainable as above, as component B, and (c) at least one colorant; (4) a process for preparation of shaped bodies, films and fibers where at least one polyisobutene modified with terminal polar groups is brought into contact with the hydrophobic polymer during processing of the shaped bodies, films, or fibers; (5) a process for coloring of fibers, films and shaped bodies in which a liquor containing at least one colorant is contacted with the composition or the fibers, films and shaped bodies; and (6) fibers, films, and shaped bodies obtained from a colored polymer composition.
