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 stabiliser having the general formula TGOT', where 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(OLJ)q,(CH2)pS-Sn(R)3-q(S(CH2)p-J)q, LCO2Sn(R)3-q(OLCO-J)q, or LSn(Y)3-q(LJ )q when n is O, from CO, E, CO-E-CO, Si(R)2, Si(OR)2, (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, -SLJ, -SLOR, -OLJ, -OLR, -S(CH2)p, each R is independently selected from R', aralkyl from C6 to C12, and aryl from C6 to C12, E is alkylene from C1 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 t o 20. An article is made from the polymer and the article is sterilised with ionising radiation. Also disclosed are novel stabilisers for use in this method.
