ABSTRACT:
Disclosed is a method of preparing a sterile medical article. A poly(vinyl chloride) or polyvinylidene chloride polymer is produced that contains about 0.001 to about 5 wt % of a metal complex having at least one anionic ligand that has at least one resonance structure in which the charge is localized on a carbon atom. A medical article is fabricated from the chlorinated polymer and the medical article is exposed to gamma radiation.
