Abstract

The invention relates to microbicidal fluid systems using antimicrobal polymers, to a method for the production of fluid systems by means of emulsion polymerization and to the use of microbicidal emulsions. The invention also relates to a method for producing microbicidal emulsions, wherein microcrobicidal polymers are produced by emulsion polymerization of corresponding monomers. Generally, emulsion polymers have higher molecular weights than polymers which are produced, for example by solution or substance polymerization. Consequently, it is also possible to produce extremely high-molecular antimicrobial polymers. The microbial polymers can contain nitrogen and/or phosphorous groups. Emulsion polymerization to form microbicidal polymers is carried out in a way known per se i.e. water, an emulsifier, at least one monomer and one thermal or photochemical radical starter are made to react in such a way as to obtain an emulsion. It is possible to add more monomer or optionally another monomer or one of the comonomers mentioned hereafter. Ionic or non-ionic emulsifiers such as polyethylene glycol derivatives, polyethylene glycol ether, especially 4-octylphenol polyethoxylate (also known under the brand name Triton) alkylbenzol sulfonates, alkylsulfates, alkyl sulfonates i.e. ethoxylated fatty alcohols, alkyl phenols or fatty acids can be used as emulsifiers.
