CHCO2H. Acrylic fibers comparable to Orlon are made by polymerizing a derivative of acrylic acid often called acrylonitrile. Other acrylic polymers are formed by polymerizing an ester of this acid, similar to methyl acrylate. One in all a very powerful acrylic polymers is poly(methyl methacrylate), or PMMA, which is sold below the trade names Lucite and Plexiglass. PMMA is a lightweight, crystal-clear, glasslike polymer used in airplane windows, taillight lenses, and light fixtures. Because it is tough, stable to sunlight, and extremely durable, PMMA can 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 resolution, respectively. The water-swollen gel was filtered by a sieve after soaking in a single day after which weighted. The water absorber (simply click the up coming document)-holding capability was calculated by the following equation:where is the load of water-swollen gel, is the burden of dried sample, and is the water absorbing capability. Figure 1 reveals the IR spectra of CMC and SAP.
Tramfloc one thousand Series is a variety of superabsorbent anionic polyacrylamide polymers. They’re crosslinked copolymers of acrylamide and potassium acrylate which are water insoluble. The polymer consists of a set of polymeric chains which are parallel to each other and recurrently linked to one another by cross-linking agents, thus forming a community.
