We argue that the linear sigma model at small external momenta is an
effective theory for the leading logarithms of chiral perturbation theory.
Based on this assumption an attempt is made to sum these leading logarithms
using the standard renormalization group techniques, which are valid in
renormalizable quantum field theories.
