Abstract
We present spectropolarimetry data on RE J1034+396, an ultra-soft X-ra y narrow-line Seyfert 1 galaxy, and find an upper limit of similar to 0.4 to the linear polarization in the optical band. This suggests that there is no synchrotron emission in this AGN, and thus it is unlikely that RE J1034+396 is related to BL Lac objects. Furthermore, any othe r polarization arising from transmission through dust, or reflection f rom dust and electrons, must be cancelled out by geometrical effects o r diluted to a high degree by unpolarized radiation.
