Abstract:
1. A sterilized article comprising a sterilized polymer composition having an as molded color, treated with a member selected from hydrogen peroxide plasma, hydrogen peroxide vapor, and combinations thereof, the polymer composition comprising a) from 80 to 20 weight % of a polyphenylene ether sulfone; the polyphenylene ether sulfone having the formula wherein n is 25 to 100 R is selected from C x is 0 to 4 and b) from 20 to 80 weight % of a polyetherimide, wherein after exposure to 300 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 as molded color of the polymer composition before the first hydrogen peroxide plasma sterilization cycle, wherein delta E is measured in accordance with ASTM D2244-05.
