Acrilan

Acrilan A brand name for a synthetic fibre, based on a copolymer of acrylonitrile with minor proportions of other unspecified vinyl monomers. See also propenenitrile. 

Acrylonitrile Polyacrylonitrile (PAN) Rugs Orion and Acrilan are copolymers with other monomers... 

Uses Polyacylonitrile is used to produce what are known as PAN fibres (Acrilan, orlon, etc.)... 

Polyacrylonitrile is used as a substitute for wool in making commercial fibres as orlon or acrilan. 

Poly(acrylonitrile) (PAN) (Equation 6.68) forms the basis for a number of fibers and copolymers. As fibers, they are referred to as acrylics or acrylic fibers. The development of acrylic fibers began in the early 1930s in Germany, but they were first commercially produced in the United States by DuPont (Orion) and Monsanto (Acrilan) around 1950. 

Propene is used as a starting material for numerous other compounds. Chief among these are isopropyl alcohol, acrylonitrile, and propylene oxide. Isopropyl alcohol results from the hydration of propylene during cracking and is the primary chemical derived from propylene. Isopropyl alcohol is used as a solvent, antifreeze, and as rubbing alcohol, but its major use is for the production of acetone. Acrylonitrile is used primarily as a monomer in the production of acrylic fibers. Polymerized acrylonitrile fibers are produced under the trade names such as Orion (DuPont) and Acrilan (Monsanto). Acrylonitrile is also a reactant in the synthesis of dyes, pharmaceuticals, synthetic rubber, and resins. Acrylonitrile production occurs primarily through ammoxidation of propylene CH3- CH = CH2 + NH3 + 1.5 02—> CH2 = CH - C = N + 3 H20. 

This compound is the starting point for the production of the synthetic fibers Acrilan and Orion.

The interior of spent cartridge cases were sampled by dry swabbing with 0.25 g of acrilan fiber for FAAS analysis (dry swabbing) or by double-sided adhesive tape (Scotch pressure sensitive tape) on the end of a suitable diameter... 

Unless stated otherwise, hands were sampled by tape lift (adhesive stub) for inorganic FDR using a 13-mm-diameter aluminum SEM sample stub with double-sided adhesive tape attached (Scotch pressure sensitive tape). Sampling of the hands and face in the outdoor firing tests in Chapter 26 employed acrilan fiber damped with isopropanol (IPA) as per the suspect sampling kit detailed in reference 190. 

After extraction of organic FDR/explosive residue, the swab is placed in a glass bottle and 75 ml of dimethylformamide (DMF) added. The DMF is allowed sufficient time to dissolve the acrilan fiber and the particle suspension is filtered through the same concentration/cleanup procedure as already described, using the Swinnex holder involved in the initial organic FDR/ explosives residue extraction. The 1-pm filter is then placed on a stub, carbon coated, and examined by SEM/EDX.
