METHOD OF IMPROVING HOMOGENEITY OF HIGH REACTIVE POLYCONDENSATE

The homogeneity of highly reactive polycondensates is improved in a process involving batch operations in a reactor, followed by extrusion and then cooling by a coolant to the point of solidification after which the polycondensates are milled and removed. The cooling is carried out with a low-boilin...

Zusammenfassung:	The homogeneity of highly reactive polycondensates is improved in a process involving batch operations in a reactor, followed by extrusion and then cooling by a coolant to the point of solidification after which the polycondensates are milled and removed. The cooling is carried out with a low-boiling liquified gas.
