Synthesis, characterization and biocidal properties of epoxy resins containing quaternary ammonium salts

SummaryQuaternary ammonium salts (QAS) were covalently-bound to epoxy resins of different DP in two steps: addition of a N,N-dialkylaminoethanethiol followed by the quaternization of the tertiary amine by an alkylbromide (C8H17Br to C14H29Br). The products were characterized by 1H NMR spectroscopy....

Description
Summary:SummaryQuaternary ammonium salts (QAS) were covalently-bound to epoxy resins of different DP in two steps: addition of a N,N-dialkylaminoethanethiol followed by the quaternization of the tertiary amine by an alkylbromide (C8H17Br to C14H29Br). The products were characterized by 1H NMR spectroscopy. The QAS-containing oligomers were used as polyols to prepare polyurethane (PU) films by reaction with a triisocyanate. The films show a good bactericidal activity against Escherichia coli, which is preserved after 6 months of immersion in water.
