A new type of chitosan derivative, dehydroabietic acid-modified chitosan (DAMC), was synthesized by the acylation reaction of chitosan with dehydroabietic acid chloride (DHAC) under microwave irradiation. The resulting product (DAMC) was characterized by FT-IR, UV, 1 H NMR, X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), and elemental analysis...
Graft copolymerization of rosin-(2-acryloyloxy)ethyl ester (RAEE) onto chitosan (Cts) was carried out under microwave irradiation using potassium persulfate as an initiator. The structures, morphology, and thermal properties of the Cts graft copolymer (Cts-g-PRAEE) were characterized by means of FT-IR, XRD, SEM, and TG. Also, Cts and Cts-g-PRAEE copolymer were used as carriers of fenoprofen calcium...
