Hydrated water gel, or water beads. Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water.Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer (SAP, also known as slush powder in dry form) such as a polyacrylamide (frequently sodium polyacrylate).
Polyacrylamide superabsorbents can absorb up to 400 times their weight in water, they are used for many applications such as reforestation, horticulture, landscaping and ornamentals. These products sold under the AQUASORB tradename, increase the water holding capacity of soils for several years, reduce irrigation time and water usage, and ...
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2.It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH 2).
Chemical structure of ethyl cyanoacrylate, the precursor to many commercial adhesives. The most common monomer is ethyl cyanoacrylate.Several related esters are known. To facilitate easy handling, a cyanoacrylate monomer is frequently formulated with an ingredient such as fumed silica to make it more viscous or gel-like.
The synthesis of poly(N-isopropylacrylamide) began with the synthesis of the acrylamide monomer by Sprecht in 1956. [13]In 1957, Shearer patented the first application for what would be later identified as PNIPA for the use as a rodent repellent. [14]
Polymethyl methacrylate is the clear break-resistant sheeting sold as acrylic glass (or simply acrylic sheet) or under the trade name Plexiglas, Perspex, etc. Polyacrylates are used in cosmetic products as rheology modifiers and film formers, and these are typically polymers of acrylic acid fluids.
