What are the properties and properties of polystyrene?
Properties of Polystyrene – (C 8 H 8) n. (C 8 H 8) n. Polystyrene. Molecular Weight/ Molar Mass. 104.1 g/mol. Density. 1.04 g/cm³. Solubility in water.
What kind of polymer is polystyrene C 8h8 N?
(C 8H 8) n is a synthetic aromatic hydrocarbon polymer with chemical name Polystyrene. It is a hard, brilliantly transparent, stiff resin. It is produced by the polymerization of styrene and is the most widely used plastic. At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows.
What happens when polystyrene is heated to 100 °C?
