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