Reactivity ratios have been determined for the anionic copolymerization of ethylene oxide and propylene oxide in bulk over the temperature range 0-80ยฐC. The ratios were obtained by two methods, the first using the variation of copolymer composition with monomer feed composition according to the May~

Copolymer compositions and reactivity ratios for the radical copolymerization of styrene with acrylonitrile have been determined by x-ray photoelectron spectroscopy (XPS). The results obtained by this technique were confirmed by elemental as well as 1 H-NMR (nuclear magnetic resonance) analysis. The
