Description
A thermoplastic polymer made from styrene. Although probably known earlier, polystyrene was described in 1839 by E. Simon of Germany, after he watched the clear styrene liquid distilled from storax resin cool then harden to form a solid mass. Polystyrene was first commercially made in 1929 by I.G. Farben (Germany) for use in styrene butadiene synthetic rubbers. Polystyrene is a hard, strong solid with good dimensional stability and impact resistance; it can be molded and fabricated. Polystyrene is often prepared as an expanded foam (Styrofoam®) using blowing agents for use in temperature and sound insulation. It can be co-polymerized with many other polymers for increased flexibility, i.e. ABS rubbers are made from acrylonitrile, butadiene, and styrene. Polystyrene is used in insulation, toys, appliances, cabinets, containers, and furniture.
