Preparation and Characterization of Chitosan/ter(GMA-MA-NTBA) Polymer Microcapsules

In this study, ter(GMA-MA-NTBA) polymer was synthesized from glycidyl methacrylate(GA); maleic anhydride (MA) and N-tert-butylacrylamide (NTBA) monomers for the first time. Chemical structure of the polymer was studied using FT-IR spectroscopy, Nuclear Magnetic Resonance (1H-NMR) spectroscopy, acidic group number and viscosity measurements and its surface morphology using scanning electron microscopy (SEM). Chitosan-based microcapsules containing different ratios of the synthesized ter(GMA-MA-NTBA) polymer were prepared and their structural stability was optimized. The microcapsules were cross-linked with glutaraldehyde to make them mechanically stronger. Chemical structure of the microcapsules was determined using FT-IR spectroscopy and their surface their surface morphology using SEM. Chitosan/ter(GMA-MA-NTBA) polymer composite microcapsules can be tested in adsorption, drug delivery and controlled release applications
