  We compute the leading-order evolution of parton fragmentation functions for
all the Standard Model fermions and bosons up to energies far above the
electroweak scale, where electroweak symmetry is restored. We discuss the
difference between double-logarithmic and leading-logarithmic resummation, and
show how the latter can be implemented through a scale choice in the SU(2)
coupling. We present results for a wide range of partonic center-of-mass
energies, including the polarization of fermion and vector boson fragmentation
functions induced by electroweak evolution.
