Abstract

PURPOSE: To prepare the title resin having improved qualities and heat-curable without emitting harmful gas, by reacting a phenol with formaldehyde in the presence of an N-containing compound, and further reacting the reaction product in the presence of an alkali metal.
CONSTITUTION: Phenol or its derivative is made to react with formaldehyde or its derivative in two steps. The initial step of the reaction is carried out in the presence of ammonia or an N-containing compound at 50W100°C for 1W6 hours, and the final step of the reaction is carried out in the presence of the oxide or hydroxide of an alkali metal or an alkaline earth metal while replenishing consumed formaldehyde. The content of the methylol residue in the produced resin is 25W35wt%. After the condensation reaction, the reaction product is heated to ≤100°C under reduced pressure to remove the water and the unreacted phenol from the resin.
