 A nonadsorbing,​ flexible polymer (in dilute solution with a good solvent) enters a pore (of diameter D smaller than its natural size, R) only when it is sucked in by a solvent flux, J, higher than a threshold value, Jc. For linear polymers, Jc=kT/eta (where T is the temperature and eta the solvent viscosity). We discuss here the case of statistically branched polymers, with an average number, b, of monomers between branch points. We find that there are two regimes, "weak confinement"​ and "​strong confinement",​ depending on the tube diameter. By measuring Jc in both regimes, we should determine both the molecular weight and the number b. A nonadsorbing,​ flexible polymer (in dilute solution with a good solvent) enters a pore (of diameter D smaller than its natural size, R) only when it is sucked in by a solvent flux, J, higher than a threshold value, Jc.
