Carbon‐13 nuclear magnetic resonance study of a divinylbenzene–p‐cresol oligomer mixture

摘要

Abstract13C NMR has been found to be useful in elucidating the structure of a complex condensation product. Study of a divinylbenzene–p‐cresol oligomer mixture has shown structural units consisting of approximately 85 2,6‐substitutedp‐cresol, 5–10 2,5‐substitutedp‐cresol, and 5–10 2‐substitutedp
