To provide a disposable diaper enabling reduction in re-wet amount and having an excellent speed of incorporating liquid regardless of concentration and configuration of a water-absorbing agent in an absorbent material.

A water-absorbing agent having excellent Gel Capillary Absorption (GCA) and Free Gel Bed Permeability (FGBP) is obtained by crushing a crosslinked hydrogel polymer obtained in a polymerization step to have a specific weight average particle diameter while fluid retention capacity and a surface tension of a water-absorbing agent are adjusted in a specific range, drying the crushed crosslinked hydrogel polymer, and then adding a liquid permeability enhancer thereto during surface crosslinking or after surface crosslinking.

A plant protein-furfuryl alcohol wood adhesive and a preparation method thereof are disclosed. The adhesive according to the disclosure is prepared from raw materials comprising, in parts by weight, 10 to 15 parts of a plant protein, 10 to 25 parts of furfuryl alcohol, 4 to 8 parts of water, 1 to 6 parts of a catalyst, and 0 to 20 parts of an additive.

Provided herein are polymer compositions comprising a polymer and polyethylene glycol (PEG)-based polymer processing aid (PPA). The polyethylene glycol can have molecular weight less than 40,000 g/mol. The polymer can be a C.sub.2-C.sub.6 olefin homopolymer or a copolymer of two or more C.sub.2-C.sub.20 α-olefins, and the polymer composition can take the form of polymer pellets; a polymer melt; reactor-grade polymer granules and/or polymer slurries; or other form of polymer composition containing the PPA and optionally one or more other additives. The polymer composition is preferably free or substantially free of fluorine, including fluoropolymer-based PPAs.

A water shedding finish for aircraft or aerospace transparencies is prepared from a paraffin wax and at least a solvent linear or branched C.sub.6 to C.sub.8 alkane solvent. The finish may further include a surfactant and similarly the solvent may be present as a co-solvent system.
