    Abstract

    We show with the help of simple Flory-type arguments that critical indices ν for the swelling of a branched polymer with a quenched system of branchings and with annealed branchings differ so that νqu < νann. This is due to the fact that the process of rearranging branchings accompanies swelling of the annealed polymer. This difference becomes drastic in some physical manifestations, e.g., behavior in capillaries. We also discuss briefly the behavior of annealed polymers in the regime of a semidilute solution.
