Synthesis of polyamidobenzhydrazides (PABH) by solution polycondensation at low temperature.
Part II. Properties of PABH
Several samples of PABH basing on p-aminobenzhydrazyde and iso- and terephthaloyl chlorides have been investigated to establish the relationship between their chemical structure and some physical and chemical properties (solubility, stability of solutions, thermal resistance, mechanical properties). A part of these studies (elemental analysis and IR-spectroscopy) has been carried out to determine the chemical structure of an aramide of unknown composition used in the manufacture of capillary fibres for the Permasep B-9 modules of Du Pont.
