Due to Sudakov double logarithms, the effect is a suppression of amplitude that grows rapidly with increasing center of mass energy leading to significant reduction of cross sections compared to tree level results. For example, the suppression factor for the cross section of $W _\textLW-_\textL$ scattering due to these corrections varies from 0.3 at the center of mass energy of $100\textTeV$ to a factor of $10-12$ at the center of mass energy of $1013\textTeV$. The modification of SM unitarity bound due to these corrections is obtained.Comment: 9 pages, 5 figures, information on v2: some minor typos fixed, published version
