During the formation of polymers, different macromolecules have different degree of polymerisation i.e. they have varied chain lengths. Thus, the molecular masses of the individual macromolecules in a particular sample of the polymer are different. Hence, an average value of the molecular mass is
The quantum mechanical methods, illustrated previously by the Schrödinger equation, are extended by the use of operators. Or, w
