For swelling in the good solvent regime, scaling models 5, 80 predict for the entanglement free limit 𝑄 ≈ 𝑁 3(3𝜐-1)/4 𝜙 0 -1/4 (v/v s ) 9(2𝜐-1)/4 (12) leading directly to the universal plot in Figure . Flory type mean field models arrive at nearly the same scaling as a function of N, but with a different scaling as a function of 𝜙 0 :
