    摘要: A composition sufficiently irradiated to achieve sterilization comprising an aromatic carbonate polymer in admixture with an anti-yellowing upon exposure to sterilization irradiation effective amount of a boron compound having part of its structure at least one
    or
    group wherein R is selected from alkyl of one to twenty-four carbon atoms, inclusive, alkenyl of two to twenty-four carbon atoms, inclusive, cycloalkyl of four to fourteen carbon atoms, inclusive, aryl of six to fourteen carbon atoms, inclusive; and substituted phenyl wherein there are one to three substituents which are the same or different and are alkyl of one to six carbon atoms, inclusive, alkoxy of one to six carbon atoms, inclusive, and halo; and
    R' is selected from the same group as R with a further hydrogen atom replaced by a bond to the second oxygen.
