Question
Define thermoplastic and thermosetting polymers. Give one example of each.
✓
Answer
Thermoplastics: These polymers are easily softened on heating, moulded and then hardened on cooling.
Examples: polythene, polypropylene, polystyrene, polyvinyl chloride, teflon, polyvinyl acetate, etc.
Thermosetting polymers: These polymers on heating become infusible and form an insoluble hard mass thus, cannot be remoulded.
Examples: Bakelite, urea-formaldelyde resins, etc.
