N-maleamic acid-chitosan was synthesized and characterized by Fourier transform infrared spectra analysis (FT-IR) and 1H NMR. The graft copolymerization of N-maleamic acid-chitosan and butyl acrylate (BA) in acetic acid aqueous solution was investigated, using the gamma-ray of 60Co gamma-irradiation method.

The polymerizable gelator N-octadecyl maleamic acid (ODMA) can self-assemble in selected polymerizable organic solvents, such as 2-hydroxyethyl methacrylate (HEMA) and methylacrylic acid (MAA) to form thermally stable polymerizable organogels. A mixture consisting of HEMA and MAA as the monomer and
