Explanation of Solution
Introduction:
Most of the stuff that is present in CD cases is polystyrene and in foam cups also polystyrene is used to make them. In making these foam drinking cups both the hard and foamy polystyrene is used. Thus, foamy polystyrene is also known as Foamy Polystyrene. Whereas in the CD cases this polystyrene is used with plastic flakes which can be easily breakable with suitable energy and they are tough and brittle.
The polystyrene is a polymer material made up of several monomerizes material called styrene. As the reaction shown below the styrene molecules in large number undergoes
Conclusion:
The polymer used is Polystyrene
