Resol beads are disclosed that are prepared in high yield by reaction of a phenol with an aldehyde, in the presence of an effective-variable concentration of a nitrogen-containing base as catalyst, a colloidal stabilizer, and optionally a surfactant. The mean particle size of the resol beads is controlled by varying the effective-variable concentration of the nitrogen-containing base in the reaction mixture, wherein increasing the effective-variable concentration of the nitrogen-containing base produces an increase in the mean particle size of the resol beads. The resol beads obtained have a variety of uses, and may be thermally treated and carbonized to obtain activated carbon beads.
