Acrylonitrile for PAN,
Acrylonitrile For Polyacrylonitrile, Acrylonitrile for polyacrylonitrile fiber,
Polyacrylonitrile (PAN) is a synthetic polymer with the linear formula (C3H3N)n. Although it is thermoplastic it does not melt under normal conditions, since it degrades before melting at above 300 °C. Almost all PAN resins are copolymers made from mixtures of monomers, with acrylonitrile as the main component. It is a versatile polymer used to produce a large variety of products, including fibers for textiles, ultra-filtration membranes, hollow fibers for reverse osmosis, etc. PAN fibers are the precursor in the production of high-quality carbon fibers.

Acrylonitrile is produced commercially by propylene ammoxidation, in which propylene,ammonia, and air are reacted by catalyst in a fluidized bed. Acrylonitrile is used primarily as a co-monomer in the production of acrylic and modacrylic fibers. Uses include the production of plastics, surface coatings, nitrile elastomers, barrier resins, and adhesives. It is also a chemical intermediate in the synthesis of various antioxidants, pharmaceuticals, dyes, and surface-active.
1. Acrylonitrile made of polyacrylonitrile fiber, namely acrylic fiber.
2. Acrylonitrile and butadiene can be copolymerized to produce nitrile rubber.
3. Acrylonitrile, butadiene, styrene copolymerized to prepare ABS resin.
4. Acrylonitrile hydrolysis can produce acrylamide, acrylic acid and its esters.
