Properties of Styrene: It is a colourless liquid, boiling point 145°C. On keeping, it gradually changes into a solid polymer called metastyrene. The polymerisation is rapid in sunlight or when treated with sodium. It shows properties of benzene ring (Electrophilic substitution) and unsaturated side chain (Electrophilic addition). However, the side chain double covalent bond is more susceptible to electrophilic attack as compared to benzene ring.
At lower pressure and temperature, it acts with hydrogen to give ethylbenzene and at higher temperature and pressure, it is converted into ethyl cyclohexane.
With bromine, it gives the dibromide.
Halogen acids add to the side chain.
Preparation of ring substituted styrenes is not done by direct halogenation but through indirect route.
When oxidised under drastic conditions, the side chain is completely oxidised to a carboxyl group.
In existence of peroxides, styrene undergoes free radical polymerisation resulting in the formation of polystyrene - an industrially important plastic.
Co-polymers of styrene with related to butadiene and other substances are also important since many of them are industrially useful products such as SBR ( A rubber substitute).
