## Abstract Wellβsized spherical beads of phenolic resin (0.3β1.2 mm) with an extremely high compressive strength (>8 kg/1.0 mm bead) and hardness (>98%) were synthesized via suspension polymerization of phenol and formaldehyde. Barium hydroxide was used as a catalyst (1.68β10.13 wt %) to get large
## Abstract βThe use of monoreactive phenol alcohols as models for the general polymerization of phenolic resins (as is commonly suggested) leads to the conclusion that such resins will contain in the earlier stages of condensation a considerable proportion of dibenzyl ether linkages. It may be con
