Question

PDI for natural polymers is generally close to (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

PDI abbreviates as polydispersity index of polymer. PDI =( overlineMw/ overlineMn) For natural polymers PDI = 1, i.e., overlineMw = overlineMn For synthetic polymers PDI >1, i.e., overlineMw > overlineMn

Q. $P D I$ for natural polymers is generally close to

$P D I$ abbreviates as polydispersity index of polymer.
$P D I = \frac{M _{w}}{M _{n}}$
For natural polymers $P D I = 1$ , i.e., $\overline{M_{w}} = \overline{M}_{n}$
For synthetic polymers $P D I > 1$ , i.e., $\overline{M_{w}} > \overline{M}_{n}$

Q. PDI for natural polymers is generally close to

PDI abbreviates as polydispersity index of polymer. PDI=Mn​​Mw​​​ For natural polymers PDI=1, i.e.,Mw​​=Mn​ For synthetic polymers PDI>1, i.e., Mw​​>Mn​
