Definitions
- the invention relates to the use and use of antimicrobial polymers in reactive formulations.
- Mucus layers often form, which cause microbial populations to rise extremely, which have a lasting impact on the quality of water, beverages and food, and can even lead to product spoilage and consumer health damage.
- Bacteria must be kept away from all areas of life where hygiene is important. This affects textiles for direct body contact, especially for the genital area and for nursing and elderly care. In addition, bacteria must be kept away from furniture and device surfaces in care stations, in particular in the area of intensive care and the care of small children, in hospitals, in particular in rooms for medical interventions and in isolation stations for critical infections and in toilets.
- Plastic cladding are equipped, which are particularly easy to handle. Next to the Undesired visual impression can also be reduced under certain circumstances, the function of appropriate components. In this context, for example, algae growth of photovoltaic functional areas should be considered.
- the copolymer produced with aminomethacrylates is only a matrix or carrier substance for added microbicidal active substances which can diffuse or migrate from the carrier substance. Polymers of this type lose their effect more or less quickly when the necessary “minimal inhibitory concentration” (MIC) is no longer achieved. From European patent applications 0 862 858 it is also known that copolymers of tert-butylaminoethyl methacrylate, a methacrylic acid ester with a secondary amino function, have inherent microbicidal properties.

- the addition of microbicidal substances such as formalin is not possible with open cooling systems, as are common in power plants or chemical plants.
- microbicidal substances are often highly corrosive or foam-forming, which prevents use in such systems.
- reactive formulations according to the invention can be fed into the process water as pure substance, blend or as a coating of further polymers in finely dispersed form.
- the bacteria are killed on the antimicrobial compounds or the polymer formulations and, if necessary, removed from the system by filtering off the dispersed polymer / blend. A deposit of bacteria or algae on system parts can be effectively prevented.
