概要 The water absorption of PTEK (0.13%) was lower than that of the corresponding PEK (0.16%), probably because of the hydrophobic nature of the sulfide group. The dielec. breakdown strengths of PTEK and PEK were much greater than that of com. available polymers. PTEK had higher dielec. breakdown strength than PEK. Although the vol. resistivity of PEK considerably decreased after water absorption, that of PTEK remained high even after water absorption. PTEK exhibited a remarkably high refractive index (nD23 1.66). α-Transition corresponding to Tg was obsd. at a high temp. (PTEK-1, 235°C; PTEK-2, 269°C) in the dynamic mech. anal. Young's modulus and tensile strength of PTEK were comparable to those of com. high-performance polymers. PTEK also exhibited excellent flame resistance. Although the linear thermal expansion coeff. of PTEK was greater than that of PEEK, it was still within a practically acceptable level.
