styrene

liquid hydrocarbon that belongs to the family of aromatic organic compounds and is important chiefly for its marked tendency to undergo polymerization. Styrene is used in the manufacture of plastics, resins, and rubbers, which are composed of very large molecules (polymers) formed by combination of smaller ones (monomers). It is also used to make polyesters and latex paints.
