Abstract:
Use of polymers which comprise (a) monomer units of the formula I in which R1 is hydrogen or C1-C4-alkyl, (b) monomer units of the formula II in which R1 and R2, independently of one another, are hydrogen or C1-C4-alkyl, or (c) monomer units of the formula I and monomer units of the formula II, for odor prevention during machine dishwashing.
