Styrene
Description
A colorless, oily liquid, Styrene was first isolated from storax in 1831 by Bonastre. It readily self-polymerizes with heat, light or catalyst. The polymerization step is exothermic. Styrene is primarily used as an ingredient in polymers such as polystyrene, rubber styrene-butadiene rubber (SBR) and butadiene styrene resin acrylonitrile-butadiene-styrene (ABS). It has also been used as a solvent in paints, lacquers and plastics. For example, it is used as a polymerizing solvent in Bio-Plastic embedding resin.
