Abstract: Provided is a production method for a water-absorbing resin in which an absorption capacity without pressure of the resulting water-absorbing resin is high and a water-absorbing resin can be efficiently obtained. The production method for a water-absorbing resin including a polymerization step of polymerizing a monomer composition containing an internal crosslinking agent and a monomer to obtain a crosslinked hydrogel polymer, and a drying step of drying the crosslinked hydrogel polymer to obtain a dry polymer, in which the crosslinked hydrogel polymer to be subjected to the drying step contains 50 ppm or more of hydrogen peroxide with respect to the solid content mass of the crosslinked hydrogel polymer, and the crosslinked hydrogel polymer is heated during the drying step so that a maximum reaching temperature of the crosslinked hydrogel polymer exceeds 160° C., and/or the dry polymer is heated after the drying step so that a maximum reaching temperature of the dry polymer exceeds 160° C.

Abstract: The cord stopper (1) comprises a plug (10), and a socket (20) into which the plug (10) is inserted. The plug (10) comprises a plug body (11) having a first string passage hole (111) and one or more elastic leg pieces (12). The socket (20) has a second string passage hole (23) capable of being in communication with the first string passage hole (111) and a third string passage hole (24). The elastic leg pieces (12) hold the string inserted and passed through the third string passage hole (24) by themselves, or together with an inner surface of the socket (20). With this configuration, when the cord stopper (1) is fixed on the string (3), it is not necessary to form an edge section of the string into a loop form, and therefore can easily be fixed. Further as the string (3) is held with the elastic leg pieces (12), the holding state can easily be released, and the cord stopper (1) can easily be replaced with another one.
