Studying the Effective Parameters on Preparation of Resole Used in Phenolic Foam

Resole resins can be cured at room temperature by using various amounts of organic or inorganic acids as curing agents. Application of acids as curing agents in processing of phenolic foams has a commercial importance due to its economic aspects. Therefore, they are more profitable. In this research, resole resin was first synthesized. Then the effect of catalyst, pH, temperature, monomers mole ratio and the time of reaction were investigated in such a way to synthesize resoles which were enough active to react with these acidic curing agents and, therefore, they were able to produce heat for making phenolic foams.
