CHCO2H. Acrylic fibers comparable to Orlon are made by polymerizing a derivative of acrylic acid often known as acrylonitrile. Other acrylic polymers are formed by polymerizing an ester of this acid, equivalent to methyl acrylate. One among an important acrylic polymers is poly(methyl methacrylate), or PMMA, which is sold below the commerce names Lucite and Plexiglass. PMMA is a lightweight, crystal-clear, glasslike super absorbent polymer price used in airplane home windows, taillight lenses, and mild fixtures. Because it is tough, stable to sunlight, and very durable, PMMA can also be used to make the reflectors embedded between lanes of interstate highways.

The dried powdered resin (0.1 g) was immersed in 500 mL distilled water and 0.9% physiological saline solution, respectively. The water-swollen gel was filtered by a sieve after soaking overnight and then weighted. The water-holding capability was calculated by the following equation:the place is the load of water-swollen gel, is the load of dried pattern, and is the water absorbing capability. Figure 1 shows the IR spectra of CMC and SAP.
Tramfloc a thousand Series is a range of superabsorbent anionic polyacrylamide polymers. They are crosslinked copolymers of acrylamide and potassium acrylate which might be water insoluble. The polymer consists of a set of polymeric chains which can be parallel to one another and regularly linked to each other by cross-linking agents, thus forming a community.
