During the past 20 years, hyperbranched polymers have been studied due to their good properties such as their simple synthetic route. In this research, a novel formation of dendrimer has been made an attempt to derived from acryloyl ammonium chloride. The structure and properties of precursor of dendritic polymer was demonstrated by UV-vis, FT-IR, 1H- and 13C-NMR spectroscopy. Dendritic polymers were prepared by the route of hyperbranched polymerization via michael addition reaction by melting to primary ammonium salt. Degree of polymerization was dependent with reaction time. Monitoring of hyperbranched polymers was performed by 15N-NMR spectroscopy. |
