A microbicidal composition comprising an aqueous solution containing a sulfur-containing quaternary ammonium ionene polymer comprising a repeating unit of formula II:
wherein X‾ is a counter-ion; R1 and R2, which can be the same or different, are selected from a lower alkyl group and -CH2-CH2-OH; A' is a radical selected from -S-, -S-CH2-CH2-S-, -S-S- and the oxidation products of -S-, of -S-CH2CH2-S- and of -S-S-; and B is a radical selected from C1-C5 alkyl, -CH2-CH(OH)-CH2-, and -(CH2)m-O-(CH2)m-, where each m is independently 1,2, or 3, and wherein said sulfur-containing quaternary ammonium ionene polymer is present in an amount effective to inhibit the growth of at least one microorganism.
