Abstract :In this study, some new chitin materials by the grafting of chitin with the monomers such as 1-vinylimidazole insert ignore into journalissuearticles values(VIM);, methacrylamide insert ignore into journalissuearticles values(MAm); and 2-acrylamido-2-methyl-1-propanesulfonic acid insert ignore into journalissuearticles values(AMPS); were synthesized. Firstly, chitin methacrylate was prepared by esterification of primary -OH group with methacryloyl chloride with a 29.24% yield by mole. Secondly, the monomer that VIM, MAm, and AMPS were grafted into a chitin methacrylate via free radical polymerization using 2, 2’-Azobisisobutyronitrile as an initiator in N, N-dimethylformamide. The graft copolymers were characterized by FT-IR spectra and elemental and thermal analysis. The substitution degree is compatible with the literature. Thus, semi-synthetic natural polymers were successfully synthesized.
Keywords : Chitin, chitin methacrylate, graft copolymer, characterization, thermal stability
