SPECTRAL AND CHEMICAL MONITORING OF CYCLO-ADDITION REACTION OF CO2 WITH POLY（MMA-co-GMA） COPOLYMERS

This paper deals with the monitoring cyclo-addition of CO;to methyl methacrylate（MMA）-glycidyl methacrylate （GMA） copolymers using spectral（;H-NMR and FTIR） and chemical（elemental analysis and titration） methods.Thus, poly（MMA-co-GMA）,was first prepared via solution polymerization.The copolymer was then treated with CO;gas flow in the presence of cetyltrimethyl ammoniumbromide as a catalyst.In terms of the carbonation reaction time,the terpolymer poly（MMA-co-GMA-co-2-oxo-l,3-dioxolane-4-yl-methyl methacrylate） was prepared in various yield of CO;fixation （>90%）.The peak intensity changes in the;H-NMR and FTIR spectra provided excellent demonstrative techniques to monitor the carbonation reaction progression.In a comparative analytical viewpoint,the NMR and elemental analysis were recognized to be the most accurate ways to follow the cyclo-addition reaction progression.However,titration was recognized to be the most preferred method,because it is a very inexpensive,facile and available method with a reasonable costaccuracy balance.
