In chemical terms, polystyrene is a long chain hydrocarbon wherein alternating carbon centers are attached to phenyl groups (a derivative of benzene). Polystyrene's chemical formula is (C 8 H

(C 8 H 8) n is a synthetic aromatic hydrocarbon polymer with the chemical name Polystyrene. Polystyrene is a hard, brilliantly transparent, stiff resin. It is produced by the polymerization of styrene and is the most widely used plastic.

Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point.

Polystyrene comes in three forms: Syndiatactic, Atactic and Isotactic. They consist of long hydrocarbon chains, with a phenyl group connected to every other carbon atom. The Syndiatactic form is highly regular and crystalline. Atactic polystyrene is irregular and amorphous (disordered) and the Isotactic form is semi-crystaline.

Jan 30, 2025 · polystyrene, a hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. It is widely employed in the food-service industry as rigid trays and containers, disposable eating utensils, and foamed cups, plates, and bowls.
