The dispersity of a polymetric sample is

During the addition polymerization, the reaction proceeds via?

The reaction rate of self-catalyzed polyestrification reaction is given as  [OH]. If [M]₀ is the initial concentration of hydroxyl and carboxyl monomers, then the degree of polymerization,  is given by

The probability of the linkage (f) in polymers when the average value of link A=40 ,B=60, C=80 respectively follows the order .

A 5 g/L polymer solution is prepared with a polymer whose molar mass is 25 kg. The osmotic pressure (in atm) of this solution at 25ºC is

(Consider RT ≈  2500 J mol^-1)
