Question
Differentiate between number average and weight average molecular masses of polymers.
Solution
Molecular masses of polymers are expressed in two different ways: number average and weight average.
Number average molecular masses of polymers is determined by colligative properties like osmotic pressure, whereas weight average molecular mass is determined by light scattering and ultra centrifugation methods.
