What is stiren monomer?

Styrene monomer is a colorless to yellowish liquid that is a precursor to polystyrene, a versatile plastic material. It is used in the production of a wide variety of products, including packaging materials, insulation, automotive parts, and toys, among others. Styrene is a flammable liquid with a sweet, floral odor that is typically obtained by the catalytic dehydrogenation of ethylbenzene. It is highly reactive and easily polymerizes, making it an important building block in the synthesis of many useful polymers and copolymers. Styrene also has a low toxicity level and is not considered a major health hazard, although chronic exposure to large amounts can cause respiratory problems and other health issues. It is commonly handled as a hazardous material due to its flammable nature.
