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

¹³C 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-substituted p-cresol, 5–10% 2,5-substituted p-cresol, and 5–10% 2-substituted p-cresol endgroups.
