Preparing sterile articles from polymers containing a stabilizer based on a poly(oxyalkylene)

Abstract

A method of preparing a sterile article is disclosed. A polymer having a halogen-containing repeating unit is prepared that contains about 0.005 to about 65 phr of a stabilizer having the general formula TGOT′, wherein each T is independently selected from R—, R—CO—, —P(R) , —P (OR) , —Si(R) , OR—Si (OR) , T′ is T or A [GOT] , each A is independently selected from LS—Sn(R) (SLJ) when n is 0, from CO, E, CO—E—CO, Si(R) , OR—Si (OR) , (Si(R) G) , (CO—E—CO—G) , (CO—G) , or (E—G) when n is 1, and from P, PO, and trimellitate when n is 2, Y is —SLJ, —SLOR, —OLJ, —OLR, —S(CH ) —J, —S(CH ) R, OLCO—J, or OLCOOR, G is (O—CH —R′CH) , J is O—(CH CR′HO)T, L is CO(CH ) , each R is independently selected from R′, aralkyl from C to C , and alkaryl from C to C , each R′ is independently selected from hydrogen, alkyl from C to C , aryl from C to C , E is alkylene from C to C , alkyarylene from C to C , arylene from C to C , m is 1 to 20, n is 0 to 2, p is 0 to 10, q is 0 to 3, and r is 1 to 20. An article is made from the polymer and the article is sterilized with ionizing radiation. Also disclosed are novel stabilizers for use in this method.
