Which process is used to make poly(styrene) from small molecules?

The process of making a polymer from its monomers is called polymerisation. In the case of poly(styrene), it is specifically addition polymerisation, where many styrene monomers add to each other in a long chain. The other terms describe different processes: - **Cracking:** Breaking large hydrocarbons into smaller ones. - **Distillation:** Separating substances based on boiling point. - **Fermentation:** A biochemical reaction, often involving yeast.
