摘要： Provided is a material capable of further extending the life of a cell including a zinc species as a negative electrode active material. The present invention relates to an anion conducting membrane formed using an anion conducting membrane-forming material, the anion conducting membrane-forming material including a conjugated diene based polymer and/or a (meth)acrylic based polymer, and a compound containing at least one element selected from Groups I to XVII of the periodic table, the anion conducting membrane having a cross-section in which a ratio of a combined area of particles of the compound containing at least one element selected from Groups I to XVII of the periodic table to a combined area of the components of the anion conducting membrane-forming material other than the compound (particles of the compound/components of the anion conducting membrane-forming material other than the compound) is 70/30 to 30/70.

摘要： Provided as a method for producing a water-absorbing resin having an excellent initial water absorption speed under load even substantially without adding a liquid permeability enhancer is a method for producing the water-absorbing resin includes the step of polymerizing a monomer while adding certain polyalkylene glycol thereto so as to generate, during or after the polymerization, a crosslinked hydrogel polymer containing the polyalkylene glycol of a specific molecular weight, in which the crosslinked hydrogel polymer has a centrifuge retention capacity within a given range and a final water-absorbing resin to be obtained has various physical properties (CRC, AAP, SFC, FSR) being within given ranges.

摘要： Provided is an absorbent body that, for example, in a case where the absorbent body has been used in an absorbent article, such as a thin disposable diaper, having an absorbent body with a low proportion of fiber material (hydrophilic fibers) such as pulp, enables the absorbent article such as a disposable diaper to have an improved liquid trapping function on second and subsequent urinations over the conventional ones and particularly to have an increased amount of liquid trapped under load on the second and subsequent urinations over the conventional ones. Also provided is a water-absorbing resin that is used in the absorbent body and has an increased absorption capacity under load on the second and subsequent urinations over the conventional ones.
The absorbent body includes a water-absorbing resin having a gel expansion force under a load of 4.83 kPa of 26 N or more.
