Abstract:
A method of preparing a sterile article comprising(A) preparing a polymer having a halogen-containing repeating unit, where said polymer contains about 0.005 to about 65 phr of a stabilizer having the general formula TGOTâ€², where each T is independently selected from Râ€”, Râ€”COâ€”, â€”P(R)2, â€”P(OR)2, â€”Si(R)3, or â€”Si(OR)3, Tâ€² is T or A[GOT]n, each A is independently selected from LSâ€”Sn(R)3âˆ’q(SLJ)q, Lâ€”Oâ€”Sn(R)3âˆ’q(OLJ)q, (CH2)pSâ€”Sn(R)3âˆ’q(S(CH2)pâ€”J)q, LCO2Sn(R)3âˆ’q(OLCOâ€”J)q, or LSn(Y)3âˆ’q(LJ)q when n is 0, from CO, E, COâ€”Eâ€”CO, Si(R)2, Si(OR)2, (Si(R)2G)r, (COâ€”Eâ€”COâ€”G)r, (COâ€”G)r, or (Eâ€”G)r when n is 1, and from P, PO, and trimellitate when n is 2, Y is â€”SLJ, â€”SLOR, â€”OLJ, â€”OLR, â€”S(CH2)pâ€”J, â€”S(CH2)pR, OLCOâ€”J, or OLCOOR, G is (Oâ€”CH2â€”Râ€²CH)m, J is Oâ€”(CH2CRâ€²HO)T, L is CO(CH2)p, each R is independently selected from Râ€², aralkyl from C6 to C12, and alkaryl from C6 to C12, each Râ€² is independently selected from hydrogen, alkyl from C1 to C12, and aryl from C6 to C12, E is alkylene from C1 to C12, aralkylene from C6 to C12, alkarylene 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; (B) making said article from said polymer; and (C) sterilizing said article with ionizing radiation.
