This equation combines relations for the size of linear chains in good solvents with the dependence of 𝑅 𝑔 2 on the number of star arms, 𝑓. Above, 𝜈 = 0.5876 is the Flory exponent, while the Kuhn length 𝑏 and the number of Kuhn segments per star polymer, 𝑁, are given in the SI Table . In this table, we compiled literature data for geometric parameters of the polymer, from which 𝑏 an 𝑁 were computed.
