概要 Novel arom. poly(thioether-ketone)s (PTEKs) bearing the 2,6-dimethyl-1,5-naphthylene unit were synthesized by the polycondensation of arom. dihaloketones and arom. dithiols in the presence of K2CO3. High mol. wt. (Mn ∼ 65 000, Mw ∼ 350 000) PTEKs were obtained in quant. yields. The mol. wt. and yield of PTEK obtained from dichloroketone and dithiol were much higher than those of the corresponding poly(ether-ketone) obtained from dichloroketone and biphenol. The use of the fluoroketone as a monomer did not increase the Mn of PTEK. The phase-transfer-catalyzed polycondensation and the polycondensation using masked dithiol and dichloroketone were also investigated. The PTEKs prepd. have high soly. in ordinary org. solvents. Flexible, transparent, and strong cast films were prepd. The PTEKs had high glass transition temps. (PTEK-1, 245°C and PTEK-2, 215°C) and 5% wt. loss temps. (PTEK-1, 435°C and PTEK-2, 436°C).
