Researchers fabricate polyacrylonitrile-derived carbon films and fibers at high temperature. Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of -100,000, about 1900 monomer units. Test Your Knowledge - and learn some interesting things along the way. While those addition polymers which are formed by polymerization of two different monomer units are called copolymers. Polyacrylonitrile (PAN), also known as polyvinyl cyanide and Creslan 61, is a synthetic, semicrystalline organic polymer resin, with the linear formula (C3H3N)n. Though it is thermoplastic, it does not melt under normal conditions. Polyacrylonitrile (PAN) is produced by a number of different methods.
