Abstract

An acrylic resin emulsion containing a quaternary ammonium salt (hybrid q‐chitosan/acrylic resin emulsion) was prepared by emulsion polymerization using an acrylic monomer with and without DAAM. DAAM was used to incorporate a functional keto group into the acrylic resin emulsion. Furthermore, a hybrid chitosan/acrylic resin emulsion was prepared for comparison. The elution of q‐chitosan in water from the acrylic resin film with a keto group was less than that from the acrylic resin emulsion without a keto group. In addition, the mechanical properties of the hybrid q‐chitosan/acrylic resin film could be modified by q‐chitosan that was crosslinked between acrylic resin particles. Furthermore, hybrid q‐chitosan/acrylic resin films had adsorption ability for formaldehyde, and the antimicrobial properties of these films were superior to those of the hybrid chitosan/acrylic resin film.
