Process for the improvement of the homogeneity of highly reactive of highly reactive polycondensates

In a procedure for obtaining a product from highly reactive polycondensate including the steps of producing the polycondensates in batch operations in a reactor, extruding the polycondensates, cooling the extruded polycondensates by a coolant to the point of solidification, milling the cooled solidified polycondensates to obtain ground polycondensates, using the ground polycondensates as a binder for composite materials by mixture with the materials, and heating and hardening the mixture to obtain the final product, the improvement comprising cooling the extruded polycondensates by using a low-boiling, liquified gas as the coolant to uniformize hardening time of the polycondensates.
