... Abstract Phenols are a class of aromatic organic compounds in which one or more hydroxyl groups are attached directly to the aromatic benzene ring, C6H6. This article describes the development of phenolic resin and the formation of novolac resin and resol resin. Phenolic resol resins are used...

... is the novolac with the lowest molecular weight. Novolacs are thermoplastic resins and require a coreactant hexamethylenetetramine (HEXA) to become thermosetting resins. The reaction requires heat. Synthesis of base-catalyzed resole proceeds via addition of formaldehyde to phenol to produce hydroxymethyl...
