Abstract
Abstract This paper describes the synthesis and characterization of some polycondensation polymers (poly- and copolyamides, polyesters) which contain cycloaliphatic units in their chains. Syntheses were carried out by a low-temperature polycondensation technique (interfacial and solution), and also by the Yamazaki method in NMP-pyridine solution using triphenylphosphite as the catalyst. The products obtained were characterized by elemental analysis, IR, and x-ray diffraction. Thermoanalytical data have shown very good thermal properties for all products, but especially for the aromatic cycloaliphatic polyamides which were stable up to 400°C.
