| titleOfInvention | High-heat-resistant, crystalline block copolymers and production process thereof |
| abstract | Disclosed herein are a poly(arylene thioether) block copolymer alternately comprising (A) at least one poly(arylene thioetherketoneketone) block having predominant recurring units of the formula ##STR1## and (B) at least one poly(arylene thioether) block having predominant recurring units of the formula ##STR2## (a) the ratio of the total amount of the poly(arylene thioether) block (B) to the total amount of the poly(arylene thioetherketone) block (A) being within a range of 0.1-9 by weight, (B) the weight average molecular weight of the poly(arylene thioether) block (B) being at least 1,000, and (c) said block copolymer having a melt viscosity of 2-100,000 poises as measured at 380° C. and a shear rate of 1,200/sec as well as a production process of the block copolymer. |
