1. Addition reaction
Under appropriate conditions, monohydroxymethylphenol continues the addition reaction to generate binary and multicomponent hydroxymethylphenol.
2. Condensation polymerization reaction
Condensation and polymerization reactions can occur between hydroxymethylphenol and phenol molecules, or between individual hydroxymethylphenol molecules.
The result of continuous condensation reaction is the formation of phenolic resin with a certain molecular weight through condensation polymerization. Due to the progressive nature of the condensation reaction, the intermediate products are quite stable and can be separated for further research.
After years of research and analysis, it is generally believed that the main factors affecting the synthesis, structure, and properties of phenolic resins are:
(1) The chemical structure of the raw materials;
(2) The molar ratio of phenol to aldehyde;
(3) The acidity and alkalinity of the reaction medium;
(4) Production operation methods.
