Molecular weight of a polymer is equal to the molecular weight of the repeat unit multiplied by the degree of polymerisation. What is the molecular weight of poly vinyl chloride (PVC), if its degree of polymerisation is 800 ?
Correct answer: A. 50000
- A. 50000
- B. 51600
- C. 49200
- D. 50800
Explanation
The PVC repeat unit is C₂H₃Cl, with molecular mass about 62.5. Multiplying 62.5 by the degree of polymerisation, 800, gives approximately 50,000.
