THE COPOLYMERIZATION OF STYRENE WITH THE CYCLIC CARBONATE OF GLYCIDYLMETHACRYLATE

The free-radical copolymerization of styrene with (2-oxo-1,3-dioxolan- 4-yl)methyl methacrylate (cyclic carbonate of glycidyl methacrylat; GM ACC) was carried out in N,N-dimethylformamide and toluene solution und er batch conditions. In toluene, a precipitate was formed during polym erization. The composition of the copolymers was determined by H-1-NMR , IR spectroscopy and elemental analysis. The monomer reactivity ratio s were calculated by different methods from the copolymer composition data. The values obtained for the different techniques were compared a nd showed a good agreement.
