ABSTRACT:
A resin for bonding polyarylene sulfides is disclosed, comprising a copolymer wherein a main constituent element of the repeating unit of the copolymer is --A--Z--R--Z--, wherein --Z--is an ester linkage; A is an arylene sulfide oligomer component block comprising one or more arylene groups; and R is an organic compound residue formed by removing one atom or one group attached to each of two carbon atoms among carbon atoms constituting either an aliphatic main chain or an aromatic ring and has at most a molecular weight corresponding to an oligomer, but is different from A. An adhesive comprising the resin and a pyrrolidone solvent is also disclosed.
