A block comprised of a copolymer is obtained by ring-opening polymerization of a cyclic polyarylene sulfide, so that a block copolymer is produced to have a maximum peak molecular weight measured by size exclusion chromatography (SEC) in a range of not less than 2,000 and less than 2,000,000 and have a unimodal molecular weight distribution in this range.
通过对环状聚芳基硫醚进行开环聚合,可获得由共聚物组成的嵌段,这样生产出的嵌段共聚物通过尺寸排阻色谱法(SEC)测得的最大峰值分子量在不小于 2,000 至小于 2,000,000 的范围内,并且在此范围内具有单峰分子量分布。
