A sterilized article comprising a hydrogen peroxide plasma or hydrogen peroxide vapor sterilized polymer composition, the polymer composition comprising from 20 to 80 weight % of a polyphenylene ether sulfone and from 20 to 80 weight % of a polyetherimide. When sterilized with a hydrogen peroxide plasma, or hydrogen peroxide vapor, the articles have surprisingly improved resistance to changes in color and clarity as well as resistance to loss of mechanical properties.
