Zusammenfassung:	The disclosure provides an associative polymer, a powder, a process for forming a paper sheet, and a process for making a powder. One or more associative polymers and one or more optional surfactants may be networked to form a wet gel and a powder may be formed from the wet gel. The associative polymer may have a weight average molecular weight of from about 10 kDa to about 2,000 kDa. A method may involve adding the powder to a cellulose fiber slurry, draining the cellulose fiber slurry to form a fiber pad, and drying the fiber pad to form a paper sheet.
