Vinyl cyanide, also known as acrylonitrile, is a colourless, odourless liquid with a sweetish taste. It is used in the production of acrylic fibres and plastics, resins, and adhesives. Acrylonitrile is also used as a chemical intermediate in the manufacture of rubber, textiles, and other materials.
When rubber is exposed to vinyl cyanide, one of the most common types of failures is swelling. This swelling can be caused by the chemical's high water solubility, which causes the rubber to expand when exposed to water. In addition, vinyl cyanide's highly reactive nature can cause it to break down the rubber's molecular structure, leading to brittleness and cracking.
