Which from following polymers is used to obtain articles like rain coats?
- A$-\!\!\left[\text{CH}_2 - \text{CH}_2\right]\!\!-_n$
- B$-\!\!\left[\text{CH}_2 - \underset{\text{CN}}{\text{CH}}\right]\!\!-_n$
- Correct answerC$-\!\!\left[\text{CH}_2 - \underset{\text{Cl}}{\text{CH}}\right]\!\!-_n$
- D$-\!\!\left[\text{CF}_2 - \text{CF}_2\right]\!\!-_n$
Solution
Polyvinyl chloride (PVC) is a widely used synthetic plastic polymer. It is water-resistant and durable, making it the primary material used in the manufacture of articles like raincoats, hand bags, vinyl flooring, and water pipes.
The monomer of PVC is vinyl chloride ($\text{CH}_2=\text{CHCl}$). Upon polymerization, it forms PVC, which has the repeating unit $-\left[\text{CH}_2 - \underset{\text{Cl}}{\text{CH}}\right]_n-$.
Answer: $-\!\!\left[\text{CH}_2 - \underset{\text{Cl}}{\text{CH}}\right]\!\!-_n$
