Water transport and drug release study from cross-linked
The release profiles of VRP from the dried and swollen microspheres cross-linked with different amounts of GA are displayed, in Fig. 6, Fig. 7, respectively, and the release from the dried polymer is relatively slower than swollen microspheres. As the transport of water into glassy microsphere is under the control of the polymer chain
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 - an overview | ScienceDirect Topics
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

Methods of synthesis of hydrogels … A review - ScienceDirect
In the presence of an additional cross-linking agent i.e. antibody, rabbit IgG was grafted to chemically cross-linked polyacrylamide (Miyata et al., 1999). In the presence of free antigen, the hydrogel showed slight swelling due to the polymer bound antigen replacement, resulting in the antibodies release along with a decrease in the cross

Polyacrylamide Gel Crystals - Home Science Tools
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.
