Notes:
(Vinyl acetate)/(glycidyl methacrylate) (V/G) copolymers were prepared by free radical solution polymerization in benzene. Copolymer composition was determined by 1H-NMR spectroscopy. Comonomer reactivity ratios were calculated by Kelen-Tüdos (KT) and error-in-variables (EVM) methods. The values reactivity ratios calculated by these methods are rV = 0.03 ± 0.01; rG = 38.9 ± 6.20 (KT) and rV = 0.03 ± 0.002; rG = 39.5 ± 1.97 (EVM). The microstructure of V/G copolymers in terms of the distribution of V and G centered was obtained from 13C{1H}-NMR spectra using the carbonyl carbon resonance signals of V as well as G units. © 1996 John Wiley & Sons, Inc.
