Polyacrylonitrile
Polyacrylonitrile (pronunciation: pol-ee-ak-ri-lo-ni-trile, etymology: derived from the Greek words poly meaning many, acryl referring to the acryl group, and nitrile referring to the nitrile group) is a synthetic resin that is made from the polymerization of acrylonitrile. It is a versatile material that is primarily used in the production of fibers used in textiles.
History
Polyacrylonitrile was first developed in the mid-20th century. It was initially used as a replacement for silk and wool in various textile applications due to its strength and durability.
Production
The production of polyacrylonitrile involves the polymerization of acrylonitrile monomers, often in combination with other monomers such as methyl acrylate or vinyl acetate. The polymerization process involves the use of a catalyst and heat.
Properties
Polyacrylonitrile is known for its strength and durability. It is resistant to most chemicals and is also resistant to UV radiation, making it suitable for outdoor use. It is also resistant to heat and flame, making it a popular material for firefighter uniforms and other protective clothing.
Applications
Polyacrylonitrile is used in a wide range of applications. It is most commonly used in the production of fibers for textiles, but it is also used in the production of water treatment membranes, fuel cells, and carbon fibers.
