How long does it take to pull an ideal polymer into a small hole?

We present scaling estimates for characteristic times tau(lin) and tau(br) of pulling ideal linear and randomly branched polymers of N monomers into a small hole by a force f. We show that the absorbtion process develops as sequential straightening of folds of the initial polymer configuration. By estimating the typical size of the fold involved into the motion, we arrive at the following predictions, tau(lin)(N)similar to N-3/2/f and tau(br)(N)similar to N-5/4/f, and we also confirm them by the molecular dynamics experiment.
