  The scattering of longitudinally polarized electroweak bosons is likely to
play an important role in the elucidation of the fundamental nature of the
Electroweak Symmetry Breaking sector and in determining the Higgs interactions
with this sector. In this paper, by making use of the Equivalence Theorem, we
determine the renormalization properties of the electroweak effective theory
parameters in a model with generic Higgs couplings to the W and Z bosons. When
the couplings between the Higgs and the electroweak gauge bosons deviate from
their Standard Model values, additional counterterms of O(p^4) in the usual
chiral counting are required. We also determine in the same approximation the
full radiative corrections to the WL WL->ZL ZL process in this type of models.
Assuming custodial invariance, all the related processes can be easily derived
from this amplitude.
