    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.

    摘要: A novel fire-retardant polymer composition is provided which comprises 100 parts by weight of a polymer such as polyolefins and polystyrenes, 1-30 parts by weight of an oxide or a complex oxide of metals such as antimony, boron, and molybdenum, and 1-30 parts by weight of heat-expandable graphite. The fire-retardant polymer composition emits less amounts of smoke and corrosive gas on burning with the characteristics of the polymer material kept unimpaired.
