Acrylonitrile

Mass spectrum of acrylonitrile

Description

A clear, colorless liquid. Acrylonitrile is the monomer used for many acrylic and modacrylic fibers (see Acrylic fiber). It is also widely used as a copolymer. Acrylonitrile is copolymerized with butadiene to produce Nitrile rubber. It is an important component in the tough resilient rubber mixtures of ABS (acrylonitrile-butadiene-styrene) and SAN (Styrene-acrylonitrile). Acrylonitrile is used as an Insecticide.
