DEFINITION

Classification: 525/140

Phenolic reactant has at least two nuclear carbon atoms directly bonded to extracyclic carbon atoms which extracyclic carbon atoms are not part of a methylol group:

(under subclass 139) Subject matter wherein the phenolic reactant has at least two of its six nuclear carbon atoms bonded directly to extracyclic carbon atoms and which carbon atoms are not part of a methylol group, e.g., 3,4,5-trialkyl phenol, etc.
