Universal QED Corrections to Polarized Electron Scattering in Higher   Orders
  We derive QED radiators for the universal corrections to polarized electron scattering. To 5th order in the coupling constant the flavor non-singlet and singlet contributions are calculated. We derive the non-singlet and singlet exponentiation of the leading terms propertional to (alpha ln^2(x))^k to all orders.
