If the number average molecular weight and weight average molecular weight of a polymer are 40000 and 60000 respectively, the polydispersity index of the polymer will be
Options
- A>1
- B< 1
- C1
- Dzero
Correct answer
A. >1
Step-by-step solution
Polydispersity index, PDI = M _w M _n where, M _w= weight average molecular weight M _n= number average molecular weight PDI = 60000 40000 =1.5 ie, >1
