Poly(arylene thioether-ketone) copolymer and production process thereof. |
摘要 |
Disclosed herein are a poly(arylene thioether-ketone) copolymer comprising (A) at least one poly(arylene thioether-ketone) segment having predominant recurring units of the formula <CHEM> wherein the -CO-and -S- are in the para position to each other and (B) at least one poly(arylene thioether) segment having predominant recurring units of the formula <CHEM> (a) the ratio of the total amount of the poly(arylene thioether) segment (B) to the total amount of the poly(arylene thioether-ketone) segment (A) ranging from 0.05 to 5 by weight, (b) the number-average polymerization degree of the poly(arylene thioether) segment (B) being higher than 1 but lower than 10, and (c) said copolymer having a melt viscosity of 2-100,000 poises as measured at 350 DEG C and a shear rate of 1,200/sec as well as a production process of the poly(arylene thioether-ketone) copolymer.
