The Effect of Temperature Reaction on Tacticity for Bulk Thermal Polymerization of Methyl Methacrylate

The tacticity and microstructure of the polymethyl methacrylate (PMMA) were studied through alpha methyl protons splitting, by proton nuclear magnetic resonance spectroscopy (1H NMR) in deuterated chloroform. The polymethyl methacrylate was synthesized at three different temperatures of 50, 150 and 250 °C via bulk thermal polymerization method. The microstructure of mentioned polymers by nuclear magnetic resonance spectroscopy, 1H NMR was determined and results were compared with statistical Bernoullian model. The corresponding probability of meso (Pm) values determined for synthesized polymethyl methacrylate at 50, 150 and 250 °C were 0.203, 0.274 and 0.356 respectively
