noun
- The quality or state of having a wide range of molecular weights or particle sizes in a mixture or polymer sample.
Usage: technical; chemistry; materials science
Examples
- The polydispersity of the polymer sample was measured using gel permeation chromatography.
- High polydispersity in the colloidal suspension resulted in uneven particle distribution.
- Researchers reduced the polydispersity by using controlled polymerization techniques.
- The polydispersity index helps determine the uniformity of molecular weight in synthetic polymers.
- Natural polymers often exhibit greater polydispersity than laboratory-synthesized ones.
