Monomer styrene is a chemical compound used in the formation of the polymer polystyrene. Its chemical formula is C8H8. It is a colorless liquid and is used in various plastic products such as bottles, food containers, household items, electronics, and automotive industries.

Monomer styrene undergoes chain polymerization with other styrene units in the process to form polystyrene. Polystyrene is a hard and transparent plastic with good impact resistance. Due to its low thermal conductivity, it may also be used as a thermal insulator in some applications.

Regarding safety precautions when using monomer styrene, the following measures should be taken:

Proper ventilation: In industrial settings, the use of monomer styrene should be done in appropriate spaces with proper ventilation. Prolonged exposure to high concentrations of styrene vapor can cause nausea,headaches, and, in severe cases, central nervous system effects.

Use of proper protective equipment: When working with monomer styrene, it is important to use suitable protective gear such as safety goggles, gloves, and protective clothing. Direct contact with the skin should also be avoided.
