polyacrylonitrile वाक्य

"' Acrylic fibers "'are synthetic fibers made from a polymer ( polyacrylonitrile ) with an average molecular weight of ~ 100, 000, about 1900 monomer units.
The properties of petroleum-based synthetic fibers, most important among them being polyamide, polyester and polyacrylonitrile, are essentially different from those of natural cellulosic and protein / wool fibers.
Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethylene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile to name a few.
Each carbon filament is produced from a polymer such as polyacrylonitrile ( PAN ), rayon, or petroleum spun into filament yarns, using chemical and mechanical processes to initially align the polymer atoms in a way to enhance the final physical properties of the completed carbon fiber.
