摘要： The invention provides a fluororesin that is less likely to suffer blistering or cracking even when rapidly decompressed from a high-temperature and high-pressure state. The fluororesin contains a vinylidene fluoride unit. The vinylidene fluoride unit represents 10.0 to 100 mol % of all the monomer units constituting the fluororesin. The fluororesin exhibits a weight loss of 0.1% or less after heated at 300° C. for two hours.

摘要： A binder and an electrode mixture for a secondary battery. The binder contains a fluorine-containing polymer containing a polymerized unit based on vinylidene fluoride, a polymerized unit based on tetrafluoroethylene, and a polymerized unit based on a monomer (2-2) represented by the following formula (2-2): R5R6C═CR7R8CO2Y1 (2-2) wherein R5, R6, and R7 are each independently a hydrogen atom or a C1-C8 hydrocarbon group; R8 is a C1-C8 hydrocarbon group; and Y1 is an inorganic cation and/or an organic cation.

摘要： A substrate processing method includes supplying a chemical solution to a surface of a substrate (step S11), supplying a rinse liquid to the surface of the substrate after step S11 (step S12), bringing a heated dry processing liquid to the surface of the substrate after step S12 (step S14), and drying the substrate by removing the dry processing liquid from the surface of the substrate (step S15). The dry processing liquid has a lower surface tension than the rinse liquid. The boiling point of the dry processing liquid is higher than the boiling point of the rinse liquid. The dry processing liquid that comes in contact with the surface of the substrate in step S14 has a temperature that is a predetermined contact temperature higher than or equal to the boiling point of the rinse liquid and lower than the boiling point of the dry processing liquid.
