Polyacrylonitrile (MW 150,000) – S1839B

What is Polyacrylonitrile?

Polyacrylonitrile is a thermoplastic polymer that is formed by the polymerization of acrylonitrile monomers. PAN is a transparent and colorless plastic that has high tensile strength, good chemical resistance, and excellent thermal stability.

Uses of Polyacrylonitrile

Polyacrylonitrile (PAN) is a synthetic polymer that is widely used in various industrial and commercial applications. PAN is commonly used in the production of fibers, films and other products. It is often used as a precursor for the production of carbon fibers, which have excellent mechanical properties and are used in various applications, such as aerospace, automotive, and sporting goods.

PAN can also be used in the production of membranes for water treatment and gas separation, as well as in the production of adhesives, coatings, and other industrial products.

Properties

PAN has a molecular weight of 150,000 g/mol (typical), a refractive index of 1.514, a melting point of 317 °C, a glass transition temperature of 85 °C, and a density of 1.184 g/mL at 25 °C. PAN has strong polar nitrile groups, making it relatively insoluble in most solvents. Chemists can convert PAN into high-carbon fibers by undergoing stabilization, carbonization, and graphitization.
