use of polydispersity index

Polydispersity (or simply Dispersity, according to latest IUPAC standards) is the measure of heterogeneity of any polymer or, in a wider context, any organic compound.
Now I can best convey the usefulness of this term using one famous maxim - a chain is only as strong as its weakest link.
Consider a polymer which has uniform sized chains all over. Such a polymer would be smooth, strong, impenetrable, don't you think?
On the other hand, a polymer with high Dispersity index. A more heterogeneous polymer. A polymer with a lot of varying chain sizes. You'd expect it to be weaker, a bit more course, raw, wouldn't you?
As a matter of fact, that's the case in reality as well. Natural polymers are known to have higher Dispersity. And natural fibers, as we all know, are not so tough, have shorter life, and are rough and coarse. On the upside, they provide higher breathability and comfort.
Synthetic polymers, however, have lower Dispersity. They are immensely strong, long lived, and generally smooth. They provide better insulation and have their own applications.
I hope you found this answer useful. Have a good day!
