摘要

AbstractThe sequence distribution of homogeneous styrene (S)–acrylic acid (A) copolymers, obtained by low conversion (<10) bulk copolymerization, has been studied by1H‐ and13C‐NMR. The reactivity ratiosraandrswere determined by the Kelen–Tudos method. The sequence distributions at the triad level were assigned and verified by Alfrey–Mayo kinetics. The sequence distributions of emulsion copolymers formed at different reaction conversions were investigated and compared with the results obtained from bulk copolymers. © 1993 John Wiley
