Preparation of Polyesters Containing Enaryloxynitrile Moiety and Their Thermal Properties
Sung-Hee Moon, Seung-Jae Lee, Jin-Bong Kim, Myoung-Seon Gong*
Polyesters containing enaryloxynitriles moiety have been newly prepared from p-bis[1-[4-(3-hydroxypropyl)phenoxy]-2,2-dicyano vinyl]benzene (3) and common diols with terephthaloyl chloride. The copolyesters have a good solubility in common organic solvents as well as polar aprotic solvents. They undergo a curing reaction at around 350 ℃ and show a 50-60% of residual weight at 500 ℃. The enhanced thermal stabilities were due to the intramolecular cyclization or intermolecular cross-linking reaction of the dicyanovinyl group incorporated into polyester by copolymerization.
