Nonquaternary poly(diallylammonium) polymers with different amine structure and their biocidal effect on Mycobacterium tuberculosis and Mycobacterium smegmatis.

Mycobacteria, especially Mycobacterium tuberculosis, are one of the most dangerous types of microorganisms to cause diseases and mortality. Due to the known distinctive structure of their cell wall, mycobacteria are resistant to majority of antibiotics and common chemical disinfectants, including quaternized low molecular weight and polymer biocides. In this work, nonquaternary protonated polydiallylamines (PDAAs) based on protonated monomers of the diallylamine (DAA) series have been synthesized, secondary s-PDAA and tertiary t-Me-PDAA and t-Et-PDAA (with Me and Et N-substituents).
