Thermosetting Polymers
- Thermosetting polymers are polymers that become permanently hard when heated and cannot be reshaped after curing.
- These polymers undergo extensive cross-linking during the curing process, forming a rigid, infusible structure.
- Examples of thermosetting polymers include Bakelite, melamine, and epoxy resins.
EXPLANATION:
- Option 1: PVC (Polyvinyl Chloride) is a thermoplastic, not a thermosetting polymer.
- Option 2: Nylon 6 is a type of polyamide, which is also a thermoplastic.
- Option 3: Bakelite is a thermosetting polymer, used in electrical insulators and plasticware due to its hardness and heat resistance.
- Option 4: "Burn-N" is not a recognized thermosetting polymer in conventional chemistry.
The correct answer is (3) Bakelite.
