Polymerization of Styrene to Polystyrene

nC8H8 → (–CH2–CH(C6H5)–)n

अवलोकन

Styrene undergoes free radical addition polymerization to form polystyrene. The vinyl group polymerizes while the pendant phenyl groups provide rigidity and transparency. Expanded polystyrene (EPS) foam is produced by incorporating a blowing agent during polymerization.

रोजमर्रा का उदाहरण

Styrofoam cups, food containers, packing peanuts, and insulation boards are all expanded polystyrene from this polymerization.

औद्योगिक महत्व

Over 15 million tonnes of polystyrene are produced annually for packaging, insulation, disposable cutlery, and electronics housings.
