摘要： Provided is a novel modified fluororesin material having a low linear expansion coefficient, a material for a circuit board, a laminate for a circuit board, a circuit board, and a method for producing the modified fluororesin material. The modified fluororesin material contains a modified fluororesin. The modified fluororesin contains a tetrafluoroethylene unit, a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene, and a tertiary carbon atom. The tertiary carbon atom is present in an amount of 0.001 to 0.100 mol% of a total amount of the tetrafluoroethylene unit and the modifying monomer unit. The modified fluororesin material has a linear expansion coefficient at 20°C to 200°C that is 5% or more lower than that of a non-modified fluororesin material. The non-modified fluororesin material contains a tetrafluoroethylene unit and a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene and containing no tertiary carbon atom.

摘要： The present invention directs to a non-aqueous electrolyte solution, including (I) at least one compound selected from the group consisting of fluorinated linear sulfones and fluorinated linear sulfonic acid esters, and (II) an electrolyte salt. Such a non-aqueous electrolyte solution has high oxidation resistance, minimizes its decomposition even when hydrofluoric acid is produced. Also, the solution is less likely to cause, in the case of being used for a secondary cell, swelling of the cell and lowering of the battery performance.
