| Abstract: | New methods for the preparation of guanidine methacrylate, methacryloyl guanidine, and its hydrochloride have been proposed, and the physicochemical characteristics of the products have been studied. A number of kinetic parameters of the radical polymerization of these monomers have been determined (the rate and the rate constant in the initial section as well as the order of the reaction rate with respect to the concentration of the initiator for methacryloyl guanidine hydrochloride). It has been found that the classical general rules are followed: The conversion increases with an increase in temperature, while the characteristic viscosity decreases. The main NMR spectroscopic parameters of polymethacryloyl guanidine hydrochloride have been determined. According to preliminary biological tests, polymers have sufficiently high bactericidal activity and can be used as stand-alone biocidal preparations or as functional additives in composite materials. |
