ABSTRACT OF THE DISCLOSURE Iodine-containing block copolymers which contain from 5 to 25% by weight of bonded iodine, and which are based on iodine-free compounds of the formula I R(AB)z I where if z = 1, R is hydrogen or a C1-C18-aliphatic hydrocarbon radical, if z ? 1, R is a z-valent aliphatic hydrocarbon radical of 2 to 8 carbon atoms, which may or may not carry up to z ethylene oxide units, z is from 1 to 6, A is a polymer or copolymer block of from 4 to 100 1,4-butylene oxide units and from 0 to 25 ethylene oxide units and B is a polymer or copolymer block of from 0 to 50 1,4-butylene oxide units and from 1 to 100 ethylene oxide units, the proportion of 1,4-butylene oxide being > 50 mole % in A and < 50 mole % in B. The above compounds can be used as active ingredients in disinfectant cleansers, for example in the beverage industry and in agriculture (dairies). The iodophores according to the subject invention can be diluted adequately and can therefore be stored virtually indefinitely at ready-to-use concentrations.
