Molecular Weight Distribution

Molecular Weight Distribution (MWD) refers to the variation in the sizes of molecules in a substance, particularly in polymers. Think of it like a group of people at a party: some are children, some are adults, and some are seniors. Each person's age represents a different molecular weight. MWD describes how many molecules fall into various weight categories. This distribution affects the material's properties, such as its strength, flexibility, and how it behaves when heated or cooled. A well-defined MWD can lead to better performance in applications like plastics and coatings.
