| titleOfInvention | Poly(arylene thioether-ketone-ketone) copolymer and production process thereof |
| abstract | Disclosed herein is a poly(arylene thioether-ketone-ketone) copolymer comprising (A) at least one poly(arylene thioether-ketone-ketone) segment having predominant recurring units of the formula <IMAGE> and (B) at least one poly(arylene thioether) segment having predominant recurring units of the formula <IMAGE> (a) the ratio of the total amount of the poly(arylene thioether) segment (B) to the total amount of the poly(arylene thioether-ketone-ketone) segment (A) ranging from 0.1 to 9 by weight, (b) the weight-average molecular weight of the poly(arylene thioether) segment (B) being at least 200 but lower than 1000, and (c) said copolymer having a melt viscosity of 2-100,000 poises as measured at 380 DEG C. and a shear rate of 1,200/sec as well as a production process of the poly(arylene thioether-ketone-ketone) copolymer. The copolymer has high crystallinity and heat resistance, uniform composition, and excellent melt stability, processability, handling properties, solvent resistance and moisture absorption resistance. |
