High energy radiation stabilization of semi-crystalline polymers |
摘要 |
A radiation stabilized and sterilized, flexible article is comprised of a semi-crystalline polymer having a crystalline content of from twenty percent to ninety percent. This polymer has been irradiated with a sterilizing amount of high energy radiation while having incorporated therein radiation stabilizing amounts of a hindered piperidine compound a benzophenone precursor sufficient to render the article substantially resistant to radiolysis while retaining its flexibility. A method for sterilizing and radiation stabilizing a semi-crystalline polymer is also part of the present invention.
