A polymer is a substance composed of macromolecules. The latter usually have a range of molar masses (unit g mol −1 ), the distributions of which are indicated by dispersity ( Đ ). It is defined as the ratio of the mass-average molar mass ( M m ) to the number-average molar mass ( M n ) i.e. Đ = M m / M n . [ 4 ]
