Abstract

The invention relates to antimicrobial polymers and polymer blends which are prepared by polymerizing a monomer of the formula I: whereR1=—H or —CH3 R2=branched or unbranched aliphatic hydrocarbon radical having from 1 to 5 carbon atoms,R3=H, or branched or unbranched aliphatic hydrocarbon radical having from 1 to 7 carbon atoms,R4=H, or branched or unbranched aliphatic hydrocarbon radical having from 1 to 7 carbon atoms,R5=H, or branched or unbranched aliphatic hydrocarbon radical having from 1 to 7 carbon atoms, andX=O, NH, NR5and, where appropriate, then mixing with at least one other polymer.The antimicrobial polymers or blends may be used for producing hygiene items or items for medical technology, e.g. as a coating, or else in surface coatings or protective paints. They may also be used in a process for eliminating/reducing biofouling in water systems.
