Q45 / 200 · Manipal (MET) 2012 · Chemistry

PDI for natural polymers is generally close to

  • A
    zero
  • Correct answer
    B
    1
  • C
    10
  • D
    100

Solution

PDI abbreviates as polydispersity index of polymer. $\mathrm{PDI}=\frac{\bar{M}_w}{M_n}$ For natural polymers, $\mathrm{PDI}=1$ and for synthetic polymers, PDI $\gt1$

Hence, the correct answer is option: 'B'.
