Corn bran (CB) was liquefied in the presence of phenol at high temperature (200°C) under high pressure (Ͼ1 atm) and the obtained liquefied products were reacted with formaldehyde to get phenolated CB/phenol/formaldehyde resins with excellent yields. The properties of the cocondensed resins were exam
## Abstract Phenanthrene‐formaldehyde resins of different oxygen content were reacted with phenol 110°C in the presence of a strong acid catalyst. Cleavage occurred at the dimethylene ether and acetal bridges joining the aromatic nuclei with the concomitant formation of phenanthrene‐formaldehyde‐ph
