The effect of temperature and monomer content on the polymerization rate of 2-ethylhexyl methacrylate

An on-line nuclear magnetic resonance (NMR) method was applied to investigate the effect of temperature and monomer content at different times during the polymerization reaction progress. The dependence of reaction with respect to monomer (1.65) was much greater than unity. An overall activation energy of Ea = 48.92 (KJ/mol) was obtained over the temperature range 50-70 °C. It was found that the rate of conversion was raised with increasing of polymerization temperature
