Melt-stable poly(arylene thioether-ketone) and production process thereof |
| abstract |
ABSTRACT Disclosed herein are a melt-stable poly(arylene thioether-ketone) having predominant recurring units of the formula and having a melting point, Tm of 310-380°C, a residual melt crystalliza-tion enthalpy, .DELTA.Hmc (420°C/10 min) of at least 10 J/g, a melt crystallization temperature, Tmc (420°C/10 min) of at least 210°C, and a reduced viscosity of 0.2-2 d?/g as measured at 25°C and a polymer concentration of 0.5 g/d? in 98 wt.% sulfuric acid as well as a production process of the poly(arylene thioether-ketone). The poly(arylene thioether-ketone) has melt stability so that conventional melt processing techniques can be applied easily. The poly(arylene thioether-ketone) is a highly-crystalline polymer whose density is at least 1.34 g/cm3 when annealed at 280°C for 30 minutes. |
