WebIn this experiment, students observe the reaction that takes place as molecules of phenylethene or styrene – the monomer – add on to each other to form the polymer polyphenylethene, commonly known as polystyrene. This process is started by adding a substance called a free-radical initiator. Web12 apr. 2024 · For instance, polystyrene, which is a polymer, is formed by polymerizing the monomer styrene. The mechanism of polymerization can vary in complexity depending on the functional groups present in the monomers being used. Simple polymerization reactions involve the formation of polymers from alkenes through free-radical reactions.
