heal.abstract	Solid-state polyamidation (SSP) processes may proceed under three different modes: in the pure solid state (mode I), through melt intermediates (mode II) and in the pure solid state accompanied by water separation in a different phase (mode III). In previous studies, on typical aliphatic diamine-aliphatic diacid nylon salts, the role of polycondensation water formed has been investigated and a qualitative model has been proposed to explain the typical mode II observed. In this work, monomer structures more organized in terms of polar coordination and rigidity are considered to reveal different modes of SSP behaviour. Ethylenediammonium maleate, ethylenediammonium fumarate and hexamethylenediammonium fumarate were selected to exhibit either coexistence of modes II and III or predominance of mode III. Interpretation of the phenomena in terms of the role of polycondensation water is again attempted. © 1990.	en
