The Compact Steep-spectrum Sources or
CSSs are physically-small objects of sub-galactic
dimensions. A large fraction of these, 
70%, which have somewhat
symmetric structure and have been named Compact
Symmetric Objects, are believed to be the young precursors of the larger
sized radio sources (Fanti et al. 1995; Readhead et al. 1996).
A minority of CSSs shows
a complex morphology or strongly asymmetric emission with respect to
the core. The structures and sizes of these are probably affected by the
ambient gas near the nucleus of the parent optical object (Pearson
et al. 1985; Fanti et al. 1990; Saikia et al. 1995).
Most CSSs show low percentage polarizations (less than 1
) at or below
5 GHz (Saikia et al. 1987). The polarization properties of CSSs
at frequencies above 5 GHz have been investigated recently by a number of
authors (for example, see Junor et al. 1996 and references therein).
Although several
well-known members of this class have low rotation measure (RM), radio
polarimetric surveys (Kato et al. 1987; Taylor et al. 1992;
Inoue et al. 1995)
have shown that many of the sources with high RM (>700 rad m-2) are CSSs.
VLA observations
by Mantovani et al. (1994) and Junor et al. (1996) on selected
samples
of CSSs have revealed several objects with large RM.
In this paper we present VLA A-array observations at 8.4 and 15 GHz of 8 CSSs, 3 of which are of subarcsec dimensions while the remaining 5 are medium sized objects. We derive their polarization properties, and compare these with our earlier observations of CSSs. These data complete the information about a sample of sources selected because there were indications (detection of low frequency variability, spectral index turnovers around 100 MHz) they were compact objects (Mantovani et al. 1992).
