Definition
Noun: A colorless, oily liquid hydrocarbon. It is the fundamental monomer unit used in the industrial production of the plastic polymer known as polystyrene.
Usage
"Phenylethylene" is a technical, chemical term. Its primary use is in scientific, industrial, and manufacturing contexts, specifically in polymer chemistry and plastics production. It is not used in everyday conversation.
Examples
- The chemical plant increased its production of phenylethylene to meet the demand for polystyrene packaging.
- In the laboratory, they analyzed the purity of the phenylethylene before beginning the polymerization process.
- The safety data sheet details the handling procedures for phenylethylene.
Advanced Usage
- As a monomer: The term is almost exclusively used to describe the substance in its role as a building block for polymers.
- The polymerization of phenylethylene yields polystyrene.
Variants and Related Words
- Styrene: This is the common industrial and generic name for phenylethylene. "Styrene" is used far more frequently than "phenylethylene" in most technical and commercial settings.
- Vinylbenzene: Another accepted synonym in chemical nomenclature.
- Polystyrene (n): The polymer formed by linking many phenylethylene (styrene) molecules together.
- Polymerization (n): The chemical process that links monomers like phenylethylene into a polymer chain.
Synonyms
- Styrene
- Vinylbenzene
- Cinnamene (an older, less common term)
Notes on Different Meanings
"Phenylethylene" has only one specific meaning in modern English: it refers to the chemical compound with the formula C₆H₅CH=CH₂. It does not have other general or figurative meanings.
