Which of the following is thermoplastic?
Open in App
Solution
The correct option is D All of the above
Explanation of the correct options:
(D)All of the above.
(A) Nylon.
- The type of plastic made of polymer resins that soften when heated and harden when cooled is known as thermoplastic.
- Nylon is thermoplastic which has a long chain of molecules with strong intermolecular bonds and it loses its shape when warm and regains when cooled.
- Condensation polymerization is used to create nylon, which is created when two functional monomers with equal amounts of amine and carboxylic acid combine.
(B)Polystyrene.
- Polystyrene is an amorphous thermoplastic with excellent gamma radiation resistance but poor chemical and UV resistance.
- A synthetic aromatic thermoplastic polymer called polystyrene is created from the styrene monomer.
(C)PVC.
- PVC is a thermoplastic material that is a synthetic plastic polymer, used in pipes, wires, etc.
- Chlorine is produced by electrolysis of salt water, and it is mixed with ethylene to form vinyl chloride monomer (VCM), which is then polymerized to create PVC resin.
- To create a unique PVC compound, the appropriate additives are added to this PVC resin.
Hence, option (D) is correct., Nylon, Polystyrene, and PVC all are thermoplastic.
