The poly dispersity index (PDI) of a polymer is (`overline(M_(w))` = weight average molecular mass and `overline(M_(n))` number average molecular mass)

A

The product of `overline(M_n) and overline(M_w)`

B

The sun of `overline (M_n) and overline(M_w)`.

C

The difference between `overline(M_w) and overline(M_n)`

D

The ratio between `overline(M_w) and overline(M_w)`.

Text Solution

Verified by Experts

The correct Answer is:
D
`PDI= overline(M_w)/(M_n)`
