Synthesis and characterization of polyaspartimides containing anthracene moiety

A new type of aromatic bis-maleimides (BMI) containing anthracene group were synthesized from bis(4-amino-3,5-dimethyl phenyl) anthramethane (BMAM) and maleic anhydride via bis-maleamic acid as an intermediate followed by cyclodehydration to BMI. The structure was confirmed by Fourier transform infrared (FTIR), H-1-NMR, and elemental analysis. In addition, a series of polyaspartimides were synthesized by the addition reaction of BMI with various diamines. The polymers were characterized by IR and elemental analysis, and they exhibit good solubility in organic solvents such as NMP, DMF, and DMSO. The polymers also exhibit good thermal stability. T-g of polyaspartimides are in the range of 212-270 degreesC and T-10% wt loss are above 406-486 degreesC.
