Poly(hexyl acrylate-co-1,4-butanediol diacrylate-co-[2-(acryloyloxy)ethyl]trimethyl ammonium chloride) can be prepared by the photopolymeirzation of hexyl acrylate and several other components. These polyacrylate-based monolithics were designed to be used for capillary electrochromatography (CEC). Mutagenicity of this acrylate ester was evaluated by the Salmonella-microsome test.
