| Abstract: | Thermogravimetry (TO) and differential thermal analysis (DTA) of poly S,S·· methylene-bis-salicylaldehyde-tetramethylenediimine (PMSATen). poly 5,5' -methylene-bissalicylaldehyde-meso-stilbenediimine (meso-PMSAS). poly 5, 5'-methylene-bis-salicylaldehydedl·stilbenediimine (dl-PMSAS). Poly 5, 5.methylene-bis-salicylaldehycle-2.6-diiminopyridine (PMSAP), and their copper (II) and nickel (II) chelates were recorded in nitrogen atmosphere up to 800 °C. Loss in weight occurs in two to three stages. The polymers and their nickel chelates indicate better thermal stability as compared to their corresponding copper complexes. DT A shows a series of endotherms with maximum in the range of 400-700 °C. |
