Abstract
This article deals with the synthesis and characterization of poly [N-(propargyloxy)phthalimide][poly (POPI)]. The polymerization of POPI was carried out by various transition metal catalysts. MoCl5-based catalysts were found to be more effective than WCl6-based catalysts. However, the polymer yield was relatively low (maximum 35%). The polymerization of POPI by PdCl2 gave poly (POPI) in fair yields in DMF and pyridine. The resulting poly (POPI)s were mostly insoluble in organic solvents. The infrared spectrum of poly (POPI) showed no peak at 2135 cm-1 due to acetylenic C≡C stretching frequency. Instead, the carbon-carbon double bond stretching frequency was observed at 1600-1650 cm-1. The TGA thermogram showed that the present poly (POPI) is thermally stable up to 160℃.
