Abstract: 

N-p-Anisylmaleimide (NPAMI) was copolymerized with methylmethacrylate (MMA) to derive copolymaleimide-acrylate poly(NPAMI-MMA). The effects of different free radical initiators: azobisisobutyronitrile (AIBN), benzoyl peroxide and hydrogen peroxide; and of various solvents: p-dioxane (DOX), tetrahydrofuran (THF), cyclohexanone (CHN), dimethylformamide (DMF) and ethyl acetate (EA) have been investigated to find the most suitable initiator-solvent system. Further, employing the equimolar ratio of NPAMI, MMA and acrylic acid (AA) or methacrylic acid (MAA) and using AIBN/DOX system two terpolymers poly(NPAMI-MMA-MAA) and poly(NPAMI-MMA-AA) were synthesized. Density measurement, solubility test, elemental analysis, IR, 1H NMR and 13C-NMR spectroscopic methods were used to characterize these polymer samples. The thermal behaviour was studied by TGA and DSC techniques.
