Description
A polymer made from the addition polymerization of acrylonitrile. Polyacrylonitrile was first made in the late 1930s and it quickly became an important types of synthetic rubber. During W.W.II, polyacrylonitrile was made into fibers for military use. After the war, DuPont began to commercially produce acrylonitrile fibers under the brand name of Orlon® in 1950. Initially all acrylonitrile fibers were called acrylic fibers. As processing variations developed, the FTC divided the types of fibers into the following two classes:
- Acrylic fibers - contain at least 85% acrylonitrile units
- Modacrylic fibers - contain 35-85 % acrylonitrile units. Pure polyacrylonitrile is also used for moldings, shoe soling and wall panels.
See acrylic fiber, and modacrylic fiber.
