Water Release from Cross-linked Polyacrylamide

Water Release from cross-linked polyacrylamide 2. Background Polyacrylamide polymer is a byproduct of the plastics industry that necessitates disposal. Cross-linked polyacrylamide has been marketed on and off over the last 20 years as a soil amendment to increase water retention and reduce irrigation frequency.

Water-dispersible nanohydrogels of cross-linked polyacrylamide

Abstract. Stable water-dispersible nanohydrogels of cross-linked polyacrylamide (PAAm) were obtained by batch (BP) and semicontinuous (SP) processes through inverse microemulsion polymerization using N,N'-methylenebisacrylamide (NMBAM) as cross-linking agent and bis(2-ethylhexyl) sulfosuccinate sodium salt (AOT) as surfactant.

Cross-linked polymer-like bulk gel used in water shutoff has very poor flowability; the viscosity is very high (>10,000 mPa·s). Uncross-linked polymer is used to increase water viscosity. A movable gel is used in between; it has the intermediate viscosity, and more importantly, it can flow under some pressure gradient. Colloidal dispersion gel

Water gel crystals, also known as water jelly crystals and superabsorbent polymer, are able to absorb up to 400 times their weight in water. Place 1 teaspoon (4g) of these small 2-4mm crystals in a quart of water, let it sit overnight, pour off the excess water and you will have over 2 cups of beautiful, large 1-2" jelly-like clear crystals.
