Disclosed is a radiation resistant propylene polymer composition comprising a propylene polymer material and generally from about 0.1 to about 5 pph, of the propylene polymer material, of a rosin material. A hindered amine is present when the concentration of the rosin material is low, i.e., below 1.0 pph. At higher concentrations of rosin material, the hindered amine is optional. Radiation sterilized articles in which at least part of the material construction thereof comprises said radiation resistant propylene polymer composition are also disclosed. |
