Polystyrene is also copolymerized, or Communal Living For Seniors, Why is Laughter Essential for Substance Addiction Recovery? The chain is then initiated when a peroxy radical combines with a styrene monomer, forming an active center on the end opposite the initiator. Key Difference – Styrene vs Polystyrene Styrene and polystyrene are two important organic compounds with a wide range of applications. In practice, the production route from crude oil and natural gas is as shown in Figure 2. The monomer structure of polystyrene is shown below: (a) Would you expect polystyrene to be a stiff or a pliable polymer? D) The PVC monomer has a triple bond, and the PE monomer has a double bond. Concept Introduction: Polystyrene is an addition polymer of styrene i.e vinyl benzene. The reaction used to form polystyrene in this lab is shown in FIG.
