    摘要: Disclosed is a method for producing polymeric polysulfides containing terminal epoxy groups, according to which polysulfides containing terminal thiol groups are reacted with an excess of epichlorohydrin and alkaline lye, water is azeotropically distilled away with epichlorohydrin, the epichlorohydrin-containing epoxidized polysulfide solution is separated from the eliminated salt, the epichlorohydrin is distilled away, and the residue is optionally purified by means of thin film distillation. The reaction product is particularly suitable for the production of high-quality sealants, adhesives, and coatings. Said product has a high degree of purity and an extremely low chlorine content. The inventive method does not require any additional organic solvents and is very environmentally friendly.

    摘要: A novel poly(arylene ether sulfone) having a sulfoalkoxy group, which has both of heat resistance and electroconductivity, is suitable as polymer electrolyte membranes used for high performance polymer electrolyte fuel cells, and does not use fluorine so that loads to the environment are small in the synthesis or disposal, a process of producing the same, and a polymer electrolyte membrane comprising the same. The poly(arylene ether sulfone) having a sulfoalkoxy group has a structural unit represented by the formula (1) mentioned hereinabove, and is produced by reacting a poly(arylene ether sulfone) having a hydroxyl group with a specific alkali metal compound and/or an organic base compound, followed by reacting with a specific sulfonating agent and then with a specific acid. A polymer electrolyte membrane is produced by film formation of the polymer.
