Abstract

A sterilized article comprising a sterilized or hydrogen peroxide vapor-sterilized polymer composition, the polymer composition comprising a polyetherimide, wherein after exposure to 100 cycles of the hydrogen peroxide plasma sterilization using a mixture of hydrogen peroxide vapor and hydrogen peroxide plasma for 30 minutes at 20 to 55° C., the color of the polymer composition of the article exhibits a color shift of delta E of 10 units or less relative to the color of the polymer composition color before the first hydrogen peroxide plasma sterilization cycle, wherein delta E is measured in accordance with ASTM D2244.
