摘要: Dimethyl and diethyl 2-(methacryloyloxyethyl) phosphonates were synthesized using the Michaelis-Becker reaction. This method of phosphonate preparation is advantageous over acid chloride route in terms mild reaction condition by employing non-corrosive, moisture insensitive reagents. These characterized mass spectrometry, Fourier Transform Infrared Nuclear Magnetic Resonance spectroscopic methods. The kinetics for bulk polymerization dialkylmethacryloyloxyethyl followed Differential Scanning Calorimetry. Activation energy was calculated Ozawa Kissinger methods found to be range 60–75 kJ/mol. Thermogravimetric analysis polymerized samples showed two-step degradation nitrogen atmosphere.
