Webrelates to the design of the phenolic base resin and the subsequent phenolic urethane polymer when reacted with a typical grade of isocyanate. For the purpose of this experimental design, two globally successful and yet different phenolic base resins were utilized, of specific interest to the authors, denoted in this case as B1 and B2. WebPhenolics are made by a condensation reaction with phenol and formaldehyde that gives off water as a byproduct. 16 A typical phenolic reaction is shown in Fig. 22. Phenolics are …
