Phenol resin can divide resol made by base catalyst and Novolak made by acid catalyst
(1) Synthesis of phenol resin that use acid catalyst
If react phenol and Formaldehyde under acid catalyst , Novolak that is solubility to ethanol and acetone as having chain structure is composed.
Do to record mol rate of aldehyde for phenol than 0.8 this time and bridge-building does not happen.
Use cross-linker such as hexamethylene-tetramine mainly to get thermosetting resin from this Novolak.
