The chemical formula of polystyrene, abbreviated as PS, is written based on the repeating unit of the monomer styrene and has many uses in the production of various plastics.
simple monomer
Styrene has the following chemical formula:
C6H5CH = CH2
Polystyrene repeating unit formula
When styrene polymerizes, the double bond is broken and a long polymer chain is formed. Its repeating unit is represented as follows:
(−CH2−CH(C6H5)−)n
Polystyrene is made by linking together many styrene units.
The benzene ring (C₆H₅) is attached to the second carbon in the chain.
Because it is a polymer, the exact molecular formula is not known and is written as a repeating unit.
