Study of Phenol-Formaldehyde Oligomers Derivatives Structure by IR- and NMR-Spectroscopy
Using IR-and NMR-spectroscopy (1H and 13C) the structure of functional oligomers based on novolac phenol-formaldehyde and polyglycidyl phenol-formaldehyde oligomers has been characterized. The structure of modified phenol-formaldehyde oligomers has been confirmed by the presence of absorption bands and proton shifts corresponding to furan ring, methacrylic fragment, peroxy, hydroxyl, and phenol groups.
