Study of anomalous couplings at a 500 GeV e+e- linear collider with polarized beams.

We consider the possibility of observing deviations from the standard model gauge-boson self-couplings at a future 500 GeV {ital e}{sup +}{ital e}{sup {minus}} linear collider. We concentrate on the case in which the electroweak symmetry breaking sector is strongly interacting and there are no new resonances within reach of the collider. We find a sensitivity to the anomalous couplings that is 2 orders of magnitude higher than that achievable at CERN LEP II. We also show how a polarized electron beam extends the reach of the collider, allowing experiments to probe different directions in parameter space. {copyright} {ital 1996 The American Physical Society.}
