Abstract
The tendency of polymers which are normally transparent after molding to undergo yellowing upon exposure to ionizing radiation is reduced by blending them with another polymer that has the effect of improving the ionizing radiation resistance over and above a mere dilution effect. The blends are moldable into medical products that can be sterilized repeatedly with little or no yellowing.
