Abstract: A method for selective production of ε-caprolactam, wherein a substance inducible from a biomass resource is used as a material; the reaction process is short; ammonium sulfate is not produced as a by-product; and production of by-products is suppressed; is disclosed. The method for producing ε-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as α-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.

Abstract: 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.
