Several Optically Violent Variable (OVV) quasars show strong wavelength-dependent linear polarization at optical and near-IR wavelengths. The wavelength dependence is in the sense that the polarization increases with wavelength. This behavior, which is quite different from that exhibited by the other type of synchrotron-dominated AGN, the BL Lac objects, has been explained by the presence of a blue, low-polarization continuum component that dilutes the synchrotron polarization of the OVV. It has been proposed that this unpolarized continuum component is "normal" quasar light and that these objects would be low- polarization, optically selected quasars if we were not located in the line-of-sight of the relativistically-beamed synchrotron jet. This program is designed to extend the study of the polarization properties of OVV quasars into the ultraviolet. Two of the brighter OVVs, 3C345 and 3C454.3, will be observed with the polarimeter of the FOS in order to measure the dilution caused by the blue continuum component in the UV. An attempt will be made to acquire simultaneous (or near-simultaneous) ground-based optical polarimetry of these variable objects to complement the UV measurements and characterize the wavelength-dependent polarization observed at longer wavelengths. In order to facilitate these ground-based observations, we request that the HST observations be made around new moon if possible (any time during the 2 weeks following a third quarter moon will allow accurate
