Abstract: An anion conducting electrolyte membrane with high performance where the electric conductivity and the water uptake are balanced, and a method of manufacturing the same are disclosed. The anion conducting electrolyte membrane comprises: a polymeric material which consists of fluorine polymer, olefinic polymer, or aromatic polymer; weak base quaternary salt obtained by the reaction of grafts introduced by graft polymerizing vinyl monomer which contains halogenated alkyl groups using radiation and strong organic bases.

Abstract: A rubber/resin composite seal material having a base material of a rubbery elastomer and a fluororesin film that comes into contact with a fluid to be sealed, bonded to the base material with an adhesive. The seal is resistant to deterioration by reactive materials such as plasma, chemicals and heat yet remains flexible and may be repeatedly compressed. The rubber/resin composite seal material may be formed into the shape of an O-ring or other sealing structure.

Abstract: The present invention provides a perfluoroelastomer composition comprising: a perfluoroelastomer having a nitrogen-containing curing site; and a catalyst mixture comprising: a tertiary amine; and an organic dicarboxylic acid represented by general formula (1) or (2) in an amount of 0.4 to 2 mol per mol of the tertiary amine: HOOC—COOH??(1) HOOC-A-COOH??(2) wherein A in formula (2) is an alkyl group having 1 to 10 carbon atoms or a phenyl group, which may be partially or fully fluorinated. Also disclosed is a perfluoroelastomer molded article obtained from the composition.

Abstract: A graft chain containing an N-vinylimidazole derivative is introduced into a polymer substrate by radiation graft polymerization to obtain an alkyl substituted imidazolium salt by a reaction with an alkyl halide, so that an anion exchange membrane with high alkaline durability, in which a nucleophilic substitution reaction and an elimination reaction are inhibited, is obtained.
