    Abstract

    We present scaling estimates for characteristic times τlin and τbr 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, τlin(N)∼N3/2/f and τbr(N)∼N5/4/f, and we also confirm them by the molecular dynamics experiment.
