DEVELOPMENT OF MATHEMATICAL MODEL AND IDENTIFICATION OF OPTIMAL CONDITIONS TO OBTAIN PHENOL-CRESOL-FORMALDEHYDE RESIN

The effect of factors on the process of obtaining phenol-cresol-formaldehyde resin (PhCR-F) has been studied. By using empirical evidence, the adequate experimental statistical-mathematical (ESM) model has been developed. Based on this model, the optimal values of the process factors for obtaining PhCR-F have been identified, bringing about both high yield and softening point of the resin. Data predicted on the basis of the ESM model were compared with empirical evidence about PhCR-F preparation.
