PDI=1 for which kind of polymers

$\begin{array}{1 1}(a)\;\text{Synthetic polymers}\\(b)\; \text{Poly disperse polymers}\\(c)\;\text{None of these}\\(d)\;\text{Mono disperse polymers}\end{array}$

1 Answer

The polymers whose molecules have nearly same molecular masses are called mono disperse polymers.For these molecules,$\bar{M_w}=\bar{M_N}$ and PDI=1.For monodisperse polymers,PDI > 1 and for synthetic polymers,PDI$\neq 1$
Hence (d) is the correct answer.
