A condensation polymer among the following is:
i) Teflon
ii) Polystyrene
iii) Dacron
iv) PVC
Answer: (iii)
Explanation: Dacron is a polymer that is formed through condensation. Condensation polymers are formed by repeated condensation reactions between two bi-functional or tri-functional monomeric components. During these polymerisation events, small molecules such as water, alcohol, hydrogen chloride, and others are removed.
