The unquenched polymer has been termed a living polymer, and if additional styrene or a different suitable monomer is added a block polymer will form. This is illustrated for methyl methacrylate in the following diagram. WebMar 15, 2024 · Complete answer: As the monomer of polystyrene is styrene, we need to first convert benzene into styrene then after polymerization reaction, polystyrene will be formed. Therefore, the synthesis of polystyrene from benzene is done as per following steps: Step-1: Benzene reacts with ethene in the presence of aluminium chloride to give ethyl benzene.
