The cross-section for bremsstrahlung production at hard X-ray energies is a strong function of the direction of the emitted photon relative to the incident electron (directivity) and of the polarization state of the emitted photon. Thus, measurements of hard X-ray polarization provide information on the anisotropy (beaming) of the accelerated electrons. I will review the (extensive) theoretical work in this area in anticipation of the recent observations by RHESSI, and the prospects of these observations as a diagnostic of particle acceleration processes in solar flares.
