heal.abstract	Solid state polyamidation of nylon salts may be accompanied, depending on the reaction conditions, by a typical transition of the process from the solid to the melt state. For an explanation of this phenomenon, dodecamethylenediammonium adipate, a typical salt with such a transitional behaviour, has been chosen for further study. The possibility of the formation of an eutectic system monomer-polymer has been excluded and the role of the water of polycondensation has been taken into account. Water quantitative determinations proved that a significant amount of the water produced, during the course of the reaction, cannot be removed out of the reacting grains. Due to the deliquescent behaviour of the monomer, it is proposed that this water accumulation results in the formation of lower melting point areas. Overlapping of the latter explains the transition observed. © 1985.	en
