RESUMO

This study analyzes a phenol formaldehyde resin and to develop it in order to reach a time reduction in the cycle time and, in second plane, to evaluate if it improves the resin characteristics in the application. The study concentrated on the condensation step, where the formation of the chain of polymer occurs. The comparison between the reaction of the phenolic resin with the reactor opened to the atmosphere through the condenser during the reflux step and that same reaction with the vent closed to the atmosphere right after the exothermal phase, also in the reflux step. The results show that a reduction of approximately half an hour is possible when the reactor is closed during the reflux step, keeping the pressure in 3x104N/m2
