Styrene (vinyl benzene, styrene monomer sm) is a colorless to yellowish oily liquid with a distinctive aromatic odor. It is sparingly soluble in water but soluble in alcohols, ethers and carbon disulfide. This valuable monomer is flammable, reactive and toxic. Styrene Monomer is a light liquid. It has a low vapor pressure and high refractive index. It is chemically reactive and undergoes polymerization readily (by heat, light or peroxide catalysts).

Styrene may undergo polymerization if the inhibitor becomes depleted, a process which, if it becomes rapid and uncontrolled, can be dangerous. This polymerization process is exothermic, evolving **8 btu/lb (*7.8 kcal/gm mole). As the styrene polymerizes, it becomes more viscous, reducing the rate at which heat can be dissipated. If the evolved heat cannot be dissipated rapidly enough, the temperature of the styrene will rise, increasing the rate of polymerization and the associated rate at which heat is generated.
The temperature may rise to the point where the reaction becomes very rapid and self-accelerating (runaway polymerization).
