Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called acrylic in the U.S, the polymer must contain at least 85% acrylonitrile monomer.Typical comonomers are vinyl acetate or methyl acrylate.trong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn.
Polyvinyl acetate (PVAc) Polyvinyl acetate (PVAc), a synthetic resin prepared by the polymerization of vinyl acetate. In its most important application, polyvinyl acetate serves as the film-forming ingredient in water-based (latex) paints; it also is used in adhesives. Vinyl acetate (CH2=CHO2CCH3) is prepared from ethylene by reaction with oxygen and acetic acid over a palladium catalyst.
