Abstract
Rosin esters are used to reduce the tendency of shaped articles made from polypropylene, especially fibers, to form malodorous decomposition products upon sterilization by gamma-irradiation. Other stabilizers normally used to prevent discoloration and degradation of polyolefins may also be present. Stabilized fibers are used for the manufacture of disposable medical products.
