  Disclosed herein are a process for the preparation of a carboxylated arylene thioether oligomer, in which an alkali metal sulfide is caused to act on a poly(arylene thioether) so as to depolymerize the poly(arylene thioether), thereby preparing an alkali thiolate-containing oligomer, and a carboxylating agent is then caused to act on the alkali thiolate-containing oligomer, thereby forming the carboxylated arylene thioether oligomer, and a process for the production of an arylene thioether copolymer, wherein the carboxylated arylene thioether oligomer alone, which has been obtained in accordance with this preparation process, or a mixture of the carboxylated oligomer in an amount of at least 50 wt.% and another carboxylic compound in an amount less than 50 wt.% is reacted with an alkylenediol or an alkylenediol and a polyester or an alkylene diol and a lactone.

  本发明公开了一种制备羧基化芳基烯硫醚低聚物的工艺，其中使碱金属硫化物作用于聚(芳基烯硫醚)，使聚(芳基烯硫醚)解聚，从而制备含碱硫酸盐的低聚物，然后使羧化剂作用于含碱硫酸盐的低聚物，从而形成羧基化芳基烯硫醚低聚物、其中，根据该制备工艺得到的羧基化芳基硫醚低聚物，或羧基化低聚物（至少 50 wt.与烷二醇或烷二醇和聚酯或亚烷基二元醇和内酯反应。

  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.

  本发明公开了一种用于粘合聚芳基硫化物的树脂，包括一种共聚物，其中共聚物重复单元的主要组成元素为-A-Z-R-Z-，其中-Z-为酯连接；A为包含一个或多个芳基的芳基硫化物低聚物组分块；和 R 是有机化合物残余物，由构成脂肪族主链或芳香环的碳原子中的两个碳原子上各去掉一个原子或一个基团而形成，其分子量至多与低聚物相应，但与 A 不同。还公开了一种由树脂和吡咯烷酮溶剂组成的粘合剂。
