Chum, H L; Kreibich, R E

An improved process is described for preparing phenol-formaldehyde resole resins comprising, replacing a portion of the phenol normally used in making resole resins with a phenol/neutral fractions extract obtained by a process of fractionating fast-pyrolysis oils, wherein the neutral fractions have molecular weights of between about 100 to about 800, and the phenol-containing compositions/neutral fractions extract is soluble in an organic solvent having a solubility parameter of approximately 8.4-9.1 [cal/cm[sup 3]][sup 1/2] with polar components in the 1.8-3.0 range and hydrogen bonding components in the 2-4.5 range.
