Abstract
In this paper, I have analysed the subarcsecond polarization structure of two high-z compact steep-spectrum quasars. Morphology suggests tha t the jets are interacting strongly with intergalactic medium. Models of bending by ram pressure equilibrium in a cooling flow and alignment of magnetic field lines by jet-IGM shock suggest that the CSS jets ar e light, supersonic and mildly relativistic. Particle energy index var iations along the jet suggests replenishment triggered by such interac tions.
