Polyamide hydrazides were co-polymerized with various amido hydrazides and di-acid chlorides. The study of polyamide hydrazides has been extended to different amido hydrazides which underwent intra molecular cyclization in the presence of polyphosphoric acid. Thermal decomposition of polymers was investigated by using programmed and isothermal thermogravimatric analysis (TGA). Reaction rates and overall activation energies were calculated from isothermal weight loss studies. In all samples, oxidation started above 250°C. Differential thermal analysis data (DTA) was used to determine the melting points of crystalline polymers. |
