<p>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)2, -P (OR)2, -Si(R)3, OR-Si (OR)3, T' is T or A [GOT]n, each A is independently selected from LS-Sn(R)3-q (SLJ)q when n is 0, from CO, E, CO-E-CO, Si(R)2, OR-Si (OR)3, (Si(R)2G)r, (CO-E-CO-G)r, (CO-G)r, or (E-G)r when n is 1, and from P, PO, and trimellitate when n is 2, Y is -SLJ, -SLOR, -OLJ, -OLR, -S(CH2)p-J, -S(CH2)pR, OLCO-J, or OLCOOR, G is (O-CH2-R'CH)m, J is O-(CH2CR'HO)T, L is CO(CH2)p, each R is independently selected from R', aralkyl from C6 to C12, and alkaryl from C6 to C12, each R' is independently selected from hydrogen, alkyl from C1 to C12, aryl from C6 to C12, E is alkylene from C1 to C12, alkyarylene from C6 to C12, arylene from C6 to C12, 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.</p> |
