<p>A ductile, gamma radiation resistant olefin polymer composition, including (a) an olefin polymer, (b) an amount of N,N-dialkylhydroxylamine which is effective to increase the ductility of the composition, and (c) a polysiloxane which contains sterically hindered piperidino groups and which is present in an amount effective to increase the gamma radiation resistance of the composition. The combination of the N,N-dialkylhydroxylamine and the polysiloxane imparts superior ductility, discoloration resistance and oxidation resistance to an olefin polymer. The composition may be used to manufacture sterilizable articles including food packaging and medical articles, such as syringe barrels, syringe plungers, tubing, tube assemblies, forceps, surgical clamps, tissue culture tubes, and fibers for surgical gowns.</p> |
