The number average molecular mass and mass average molecular mass of a polymer are respectively 30,000 and 40,000. The poly dispersity index of the polymer is

Options

  1. A< 1
  2. B> 1
  3. C1
  4. D0

Correct answer

B. > 1

Step-by-step solution

P D I = M - w M - n = 40,000 30,000 So, the value is more than 1.
