      Synthesis of a novel co-polymer made by the addition polymerisation between MEGDMA and 4-AB by aza-Michael addition (AMA) polymerisation method is a fascinating field of research. The present investigationyielded a hazardous metal catalyst-free and toxic solvent-free methodology. The AMA polymerisation was carried out at five different [$M_1/M_2$] values under N$_2$ atmosphere at 100$^{\circ}$C for 2 h. Thus, obtained co-polymer was characterized by Fourier transform infrared spectroscopy, UV–visible reflectance spectroscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis and scanning electron microscopy (SEM). The SEM image confirmed the formation of polymer nanoparticles. The non-isothermal degradation kinetics was followed with four different models, such as Flynn-Wall-Ozawa, Auggis-Bennet, Kissinger and Friedman method. Among the modelsused, the Kissinger method yielded the lowest degradation kinetics. The degradation kinetics of the co-polymer was followed with the help of model-free methods. Moreover, it was critically compared with the literature.
