초록

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. $MoCl_5$-based catalysts were found to be more effective than $WCl_6$-based catalysts. However, the polymer yield was relatively low (maximum 35%). The polymerization of POPI by $PdCl_2$ 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 $C{\equiv}C$ 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 $160^{\circ}C.$.
