  We present polarization images of 9 radio-loud (RL) quasars from the VLA
B-array at 6 GHz. These quasars belong to the Palomar-Green (PG) "blazar"
sample comprising 16 RL quasars and 8 BL Lac objects. Extensive polarization is
detected in the cores, jets and lobes of all the quasars, with cores primarily
displaying magnetic (B-) fields transverse to, and jets displaying fields
aligned with the jet direction. Hotspots display either transverse B-fields
signifying B- field compression at terminal shocks or more complex structures.
The fractional polarization in the cores ranges from 1-10% and jets/lobes from
10-40%. Several of the quasars show distorted or hybrid FRI/FRII radio
morphologies with indications of restarted AGN activity. We attribute this to
the optical/UV selection criteria of the PG sample that remains unbiased at
radio frequencies. The in-band spectral indices of the radio cores are
relatively flat while they are steep in the hotspots. This is consistent with
the polarization structures where the hotspots appear to be locations of jet
bends or bow-shocks. We present global properties for the entire PG "blazar"
sample. We find that jet powers correlate with accretion rates for the quasars;
higher accretion rates result in more powerful radio jets. A correlation
between the radio core fractional polarization and the 150 MHz total radio
luminosity for the 9 quasars studied here may imply that more organized
B-fields at the jet bases lead to higher core fractional polarization and to
more powerful radio jets.
